Engine oil choice
 

Hi guys,

My car is due for oil change at 1K, since MM has yet bring in their Rotary oil, I am considering to get any of the list below.

Which will be a better choice, and if anyone has tried them. Please advice. Thanks.

Trust F2 RE-Spec

Trust F3 RE-Spec

or

HKS RE Racing
http://www.hks-power.co.jp/products/...ne/oil_04.html

Currently using Trust F2. Have used HKS too. Both seems ok to me.

Thanks UG.

BTW, anyone has a can of Trust F2 RE for sale (heard a few RX8 owners went to Autobacs and grabbed all). I have checked with Autobacs, they said the supplier has stop supplying Trust to them.

MM has confirmed no stock for Rotary oil but can place order and cost $251 for 4 ltrs. They are getting the Mazdaspeed Rotary 1 oil, which Cartonic also carry and selling much cheaper but still expensive IMO.

Huh autobacs no more ah? Wah piang, in that case left with only HKS can buy from outside. The rest need to order.

MM's rotary oil cost $241 for 4 litres...wah lau that is the most expensive 'snake' oil!!! :eek:

I think i wil go mineral........SXXT!!!!

This Oil issue is really getting out of hand. Couple of post ago, someone posted using Trust Rotary Oil, now Trust F2 (which isn't a rotary oil) for what ever reason has been snatched up. And MM is doing a daylight robbery for asking freakin $251 for engine oil! What the hell is going on here!
Frankly, BlackAero, and who ever got their car from MM, you guys should protest and insist on using nothing else but only the rotary oil! What the hell MM think they're doing, selling rotary engine yet not servicing it the right way! Don't let them get away with things like this man!
By the way Aero, if you intent to go back to rotary oil, avoid using synthetic oil on your next change, just stay with any mineral base oil til the rotary oil comes in.

M-Ster, Trust F2 is RE-Spec...there is Trust F3 RE-Spec also... But now Autobacs does not stock it, so duno where to get ....

MM service advisor confirm that Shell mineral oil meets or not above the requirments of the rotary and hence they will be using that.

Rotary oil will not be available unless you pre-order at the premium price from MM parts dept.

Which one in Shell? Helix? Any numbers or simply grab the Shell Helix off the shelf?

I am not familiar wif mineral. Sorri......

Mster, care to voice ur tots on discouraging Aero from Syn? I am interested dats all.

Cheers

Thanks for clearing, I was down at Autobacs and the Trust F2/3 that's left wasn't RE-spec. and I thought that was what people are snatching up.

I'm having these thumping sound coming from the exhuast system since after I change to synthethic, I'm not sure if that's the cause. Anyway, it sounded like some kind of combustions happen only at the header area and amplified as it exit after the cat. According to the workshop, it's not normal, they have to send my ECU back to Japan to dyno.
Anyway, I've being trying to get my hand on some rotary oil, hopfully to change out what I have in the engine now(syn).
As we all know, the basic oil change routine only drain out about half the oil in the engine, for anyone who wanna keep to mineral/dino (which is original that comes in the car) should keep to it, rather than switching to syn then back to dino. Then one wouldn't end up having different mixes of oil in the engine.

Eh ur second quote was not quoted by me leh? Strange...

Sorry, did a bad cut and paste job, that was meant for Neon. :o

M-ster, so ur car is out of action for 2 weeks?

No, not yet. I'm still driving it. Going away in Sept, then I'll leave my car with the work shop. Partly dragging it also, I wanna have an oil change (back to mineral base) and see if there's any diff. Always prefer to try the basic fix first before they start taking the car apart.

M-ster, keep us posted on the ECU.

Actually, since they are sending your ECU to Japan, might as well send to the tuners for something different, eh? ;)

Well the only thing I hope by sending the ECU up is also to get the lastest re-flash with it. Hopfully when I get it back all bugs will be fixed and I'll enjoy the 18km/L claims that they made:)

Thumping sound? Hmm I do have some 'poof-poof' sound during idling after I change to the HKS open pod filter...

Hmm, sounds like a common enough situation. Some people says it's normal, but the workshop guys think otherwise. Maybe I should leave it, but then it's kind of bugging me...:(

Well when accelerating it is smooth, thus I am not that bothered by it. The rotatry idling is definately rough and you can see the oil pressure is also fluctuating. I guess maybe with the M-Flash or ? Flash, this will solve it.

But I do think that Mazda Japan must be responisble of supporting Mazda Cars, irregardless whether we buy from PIs or MM. Maybe we can petition to Mazda Japan...or maybe initiate a class action :cool:

I second dat! Maybe we should all go to Paya Lebar MM and use our 8 to block the entrance. Haha.

Mster, keep us posted man. I would really love to know whether the flash can cure dat. If it does, i will be really disappointed with ALL PIs!

Hi guys,

If I'm not mistaken, the japanese engineer who is reputed to be very experienced with rotary engines said synthetic oil was better for the engine, right? Was he referring to only rotary engine oil? or any kind of synthetic engine oil?

Hi Melo,

I posted something on that after Sato san gave the talk. If I remember correctly, he swears by synthetic oil. "To win a race - use Castrol", 10W60. Something like that.

-Ringer-

Hi Ringer

Thanks for your info. I'm assuming that Castrol oil he mentioned isn't specially for rotary engines?

There are so many different views on what oil types to use, it can get a little confusing. From scanning the forum pages, sounds like alot of the SG RXs are going on rotary engine oil.

Perhaps thats the safest option...

Confirm Castrol RS? Isnt dat 5-50 onli??

Melo/Neon,

Sato san's talk was on the rotary engine. He worked on many RX7s. He definitely recommends synthetic, especially Castrol - "the molecules are more slippery". Makes a difference in racing - "to win a race use Castrol 10W60" (I guess this is not off-the-shelf).

Personally, I use HKS RE Rotary synthetic oil 10W40. Looking out for Trust rotary synthetic oil. Hey, whoever bought all the stocks from Autobacs please let me have some.

I also top up with Mobil1 Super Syn 0W40 (about 1/2 litre per 3000km) since HKS RE oil is not available in 1 litre bottles. I am comfortable with all the products i mentioned in this post. Sometmes it's a psychological thing once you are already using a premium product.

I will not use ordinary dino oil. The only dino oil I might try is Mazda non-synthetic rotary oil, the one mentioned in many threads but no one seems to be able to get their hands on it. If I use dino, I'll change it every 3000km/3mths.

-Ringer-

Don't remember the Mazda Singapore's RX-8 test drive to have this problem. Anyone with Mazda Singapore's RX-8 can confirm this?

U bet. I have tried to source for 10-60 but cant find even in most reputable car shops.

Using RS now. Not too bad, at least cheaper than HKS. I wouldnt mind tryin TRUST too. I trust them...:D:D:D

I didnt switch back to HKS becoz RS gives the same idling if not slightly betta than HKS i feel. Oil Pressure at idle is about da same with RS slightly higher too. I like. keke...

Awaiting TRUST F2 Rotary man......haiz...Bo liao

A little update.

I've just did my 5k service.

On my fisrt 1k service I have changed to synthetic. And if you did read my earlier post (in this very thread) I have this thumpping/blurpping sound at idle.

Back to my 5k service, I've change back to mineral base oil (as we all know there're about 8 liters of oil in our engine, and normal oil change only swap out 1/2 of it) so it left with about 25% synthetic in the engine, the sound that I was describing has reduced!!

The thumping sound is still there but much lesser now, not sure if the oil is the main cause, but seems to be the closest things i can think of. Will monitor it further. So for those who's car is making the same sound as I doe, you might wanna try this.

Guys,

Trust F2 RE is back in stock at Autobacs. I also noticed they also sell Mazda Engine Oil 10W-30 but not sure if it is applicable for our Rotary.

There is also the RMagic manual gear oil 75w-90 but only 3 cans left but damm expensive $220 each. Remember to use your AA card and get 5% discount.

Grab it b4 it runs out again. Cheers.

Do you know if the Trust F2 RE and the Mazda engine oil are synthetic or mineral base??

Thanks

guyz,the RE spec oil @ autobacs in liao leh...juz grabbed a can 2day... ;)

M-ster..the Trust F2 RE Spec is synthetic...not too sure with the mazda ones...but i bet it is mineral base.

In autobacs, also saw R-Magic gear oil for Rotary cars :cool:

Hi guys,

I got the info on MazdaSpeed rotary oil and Trust RE oil from BlackAero.

Just went down to Autobacs and bought a 5L tin of TRUST F2 RE Rotary 100% Synthetic (Chinese script says 100% man-made) oil @S$138. Fair price, good size packaging! especially when RX8 needs 4+ litres. Will change at 12mths/12,000+km around 12 Sept 1st year anniversary!

BlackAero informed me that the MazdaSpeed Rotary oil is dino and @S$50/L! Way too ex for me. Especially to my mind dino oil has limited longevity so would need to change at 3mth/3000km (or after one race as intended by MazdaSpeed??).

There is another Mazda (not MazdaSpeed) dino oil a picture of which appeared in one of the threads (Australia??). That is different from the $50/L MS RE oil that BlackAero got. I think that was formulated for the Australia market since the RX7 days.

I'll let you know how the TRUST RE feels next month.

-Ringer-

Hmmm... someone from autobacs seems to be observing the forum here, bringing all the oil that we need for our baby 8. 1st trust rotary oil now original mazda oil:)

Hi ringer, are there still alot of oil or only left with last few can laying around, will probably pop by over the weekend, hope i won't make a empty trip again.

M-ster,

There were 7 tins of 5L Trust RE oil left on the shelf yesterday. Not sure about backroom. In my haste I did not notice the Mazda 10W-30 oil. Damn should have checked it out.

-Ringer-

The Mazda oil looks like for normal car...not for rotary engine...

Did oil change at Autobacs today (mileage 1300 km) with Trust F2 RE oil. I notice that my engine idle is much smoother especially after startup. There used to be a slight burbling sound when I previously started the engine and now it's gone.

Was down at AutoBacs yesterday, they have got the R-Magic EngineOil for the our Rotatry babies as well! Quite expensive as compare to the Trust though, couldn't remember the exact price but its in the $280 mark. Well for those whose got some extra $ and wanna pamper their baby might wanna have a go with the R-Magic!

hi all,

Went to autobacs for my 1st 1000 km oil change on sat.
used trust f2 rotary oil.. no problems after..

thanks for the forum's advice.

DAVE

Wad kinda problems u toking about?

Popping idle? Rough Idling?

Neon

read carefully

Eh, Davester's first post in this thread le.

He didnt state his problems le....:P

No problems so far man... its all good...

dave

Hi Guys,

Pleased to report on the TRUST F2 RE rotary syn oil (15W50) as promised.

The engine sounds smoother and more muffled compared to HKS RE oil (10W40) which sounded more sporty. I attribute this to the difference in viscosity. As usual feels very fleet footed whenever oil changed and rev'd to 9500 rpm freely. Maybe attaining 9000 rpm is a tad easier.

Another report : MazdaSpeed air fliter. Definitely worthit. Easier breathing is immediately apparent, resulting in smoother and faster progress from standstill and clearly smoother and easier gear changing. Yes positive effect on gear change due to no hesitation.

-Ringer-

Yup, can attest to Ringer's comments on the MS airfilter. Definitely more eager.

Hey Ringer, show us a pic of your carbing strut brace, man!

errrrr.....newbie so quite unsure and sounds corny. do you guys change your own engine oil or let autobacs do it, also since it is under warranty is it allowed or must you go back to the dealer workshop.

Hi Fab8,

I'll show you at the next meetup.

sgrenesis,

Mine's JDM from PI, GR. I let them do all the work at trusty FMGR (and pay lah). Never change your own oil unless you are a pro with proper, environmentally friendly way to dispose of used oil.

-Ringer-

here here! Well said Ringer.
