oh man, i dont even know what to say anymore, lemme play lady gaga's "SPEECHLESS", even tho i dont like her and her songs barely makes sense. the title is my answer to your reply.

 

LOL @ "what the manufacturer recommends"

tell me sir, why has the manufacturer recommended one thing in the US and a different set of recommendations in other countries?

 

that word reminds me of the classic line in the movie "snakes on the plane"

 

cuz mazda(manufacture) knows best and we dont know ****. they dont have to care about cafe, nothing, 5w20 works cuz they said so.

oh wait, manufacture recommend us to service our cars ONLY at dealerships, no one seems to listen to that. mmm did GTdave listen? maybe, i know i never did, im a bad boy, evil and im going to hell with my8 for sure. PANIC!

 

I wasn't trying to spark an argument between peoples. Just Repeat what I was told by the dealership. If I'm in idiot for parroting what the last Technician told me, then shoot me.

 

Bang!

 

 

i keep hearing people putting down the mazda motor oil 5w20, but if you use their oil and premix 4-6oz(good quality 2stroke), wouldn't that make up for the difference. Instead of having to drop the money on synthetic oil, and risk voiding the warranty. I figure it'd be harder for them to notice the premixing then the synthetic oil.

 

Synth+viscosity and premix address different issues. Besides... it's highly unlikely that a dealer would pay a lab to perform an oil test to determine the oil's type and viscosity.

 

lol, fair enough.

 

FYI, one of the finest synths has had a recent re-branding -



formerly Syntec 0w30, made in Germany.

 

Holy smokes, I might be going back to a 0w-30 then.

 

would they pay that much to run a lab test to see what oil u ise? no, they will not, we are talking about hundreds if not thousands.

5w20 is 1 issue, nothing to do with synthetic or not. and has nothing to do with premix

what the hell todd, u trying to tell me u never seen this? i jesus i made so many post about it years ago ... where have u been lol the tbn of his oil is like 8.9 . not bad. i had a lot of them b4. used hem on my 8 maybe couple of times the rest goes to my other 3 cars. lol

it used to cost 27bux for 5 qts and mobil1 or k&n filter aboiut 2 yrs ago, i stock that **** up like nuts.now it cost 32.99 ... at this price, i rather just get mobil1 0w40, which is also pao 4 oil and has 13 tbn or something

 

u trust ppl at a dealershipppppppp????????? waaaattttttt?

mm, i only trust 1 guy at wayne mazda. thats about it. he is a rotorhead himself so its trustworthly he also told me a lot of stuff that some naysayers here said no. including synthetic, hah!

 

lol..

Both of my cars have not set foot in any Mazda Service Department since I drove off the showroom floor, and I have no intention of ever taking them there...unless I need warranty...so far so good.

Having worked in the 'system' if they think I am giving them $90+ an hour for a grass cutter mechanic to touch my car you have another thing coming...I gave the dealership most of my money..they are not getting anymore..

 

I've been aware of the specific blend of Castrol that was used in Germany as we've discussed it a lot. Last I remember, it wasn't available anymore.

 

I dunno about west coast, I was at auto zone 2 weeks ago they still carry the made in Germany one

 

O

Good point. I think I paid dealership twice. First time was I didn't know ****, car had air system problem cel, and serious lack of power. Didn't know it was clogged cat. Charge me an hour of labor didn't do ****.

Last time was they said my oil filter was leaking, changed it for me without asking, and charge me 35 bud. I was about to say take that **** off but I was in a hurry, so I paid and just left, I know its just the greddy adapter leak. ******* monkeys

 

i've had my 8 for a long time, engine has lasted 7 years, getting a new one now. But i am one of those that did take it too the dealership for oil changes and maintenance, don't get me wrong i sneaked in the odd thing like decarb and uppercyclinder lub/cleaner. I also did certain maintenance more often such as tune ups, plugs/coils, etc. But the main reason is the warranty, i've seen many people shot down and try to fight it and get no where. My oil changes at the dealership ran $38 dollars, thats filter, oil, labour, and disposal. I've considered doing it myself, but price wise and warranty wise it wasn't worth it for the first while due IMO to price and warranty coverage. My engine warranty will be up shortly and now that i'm getting the new engine i'll be doing things differently. But i can understand why people are hesitant to buy a new car and say hey, f-u- mazda i'm doing everything myself and risk voiding the warranty.

 

NO car maker can void your warranty in the USA or Australia or most other continents.

Provided, you can prove that your car has had regular maintenance.

IF you modify your car to change specifications is another matter again, it depends where and what you mod, usually a maker will void the location of the mod install.

 

I used and tested the GC 0W-30 and after only 1500 miles it was tested and did not do to great considering how long it was in the engine. I know the tests are not perfect but the Mobil1 0W-40 has held up much better over time and mileage.

 

I hav3 used both m1 0w40 and their 15w50. 0w40 works really well, still have a few left

Time to stock those suckers up

 

Glad this thread is here. Brought RP in with me for my last oil change, and the one guy in the shop who actually knew what a rotary was tried to talk me out of using it. Gave me the old "synthetics break down seals" story.

I've only had my 8 for a few months, and was pretty concerned. I only used RP due to a suggestion made in these forums, and was glad to see the seal breakdown story debunked here when I read thoroughly.

Not sure about others, but I get a good 1-2 more MPG with RP than I was getting with the previous oils.

 

We get oil tested and analysed at our shop for about $30 I don't see why a dealership can't get oil done for the same cost. One of the tests that are done with that is viscosity, so don't think a dealer can't do that simple check if you have an engine problem.

 

I would send your RP in to get tested and then compare the results to the other test results from other oils in the UOA thread. The RP has not done so great honestly, but their marketing department does a great job hyping it up.
