how many quarts needed for oil change?
 

getting ready to do the 1st oil change. how many quarts of oil are needed?

Do you have an owners manual?

the car was purchased for my girlfriend but the owners manual is in the glove box with her right now. so it is of no help

oil change
 

we buy 6 and have some left it save a second trip to the store...

Get the special 5.5 quart jug.

Do the oil change, put around 4 quarts. Run car for a couple of seconds, shut off and check oil stick.

depends on which technique you use if you jack up one side of the car(drivers) you can get about 4.5 or 5 qts out if you drive up on rams it's about 4 so buy a 5qt container and put 4 in check and add till full....then whatever is left keep for fill ups in between oil changes

i put 3.7 thts what dealer recommends

4 quarts will do it.

any special type or preference for oil filters?

mazda OEM or one from Atkins Rotary.

sorry, i'm new to all this. another question i have on the subject is; driver under normal conditions for the most part, do you have to add oil between 3-5k oil changes?

I use FRAM but everyone i know says they are terrible but that's what i use

Just for future reference ( and so you won't get flamed in the future), you can download the owner's manual online from Mazda in PDF form. Even better than the hard copy, since you can search it.

To answer your question:
-Buy 4 quarts of oil. Fill 3 quarts and then fill the last quart until you have what you need.
-Mazda OEM filter, plenty good and relatively cheap (from Rosenthal)

Yes. It varies, but it will be around a quart every couple of thousand miles.

Since there are 1.8 quarts between the high and low marks on the dipstick, you might make it from one change to the other without topping off. But IMHO it's best to not let it get more than a quart down.

Personally, I top off when it's half a quart down. But I enjoy peeking under the hood and the fetish aspect of measuring out half a quart from quart bottles.

Ken

haha yeah anytime to open my hood i always take the chance haha....ahhhhhh Renesis multi side port!!!!

Whatever you do, don't start asking about conventional versus synthetic oil.

:eyetwitch

FRAM!!!!??!?!? Fram is HORRIBLE... cheap and restrictive...:banghead: Heard alot from my instructors and Tech Mentors about how fram fuked up there customers coming back with bits and pieces of the filter stuck and logged in to the oil pump... =/

for your 8's Sake...change to something else... :)

OE Oil filter will do, I can get them for 4 bucks each cuz Im in their motorsports program. but you can probably get them around 5 bux each. not bad for every couple thousand miles right ?

if you want "better" oil filters, you can try WiX filters. about 6 bux.

K&N has oil filters too (1008 or 1010 will fit, 1010 just taller) and it has a 1" nut top for eas*ier* removal. about 10 bux. up to you.

For oil, 4 quarts is enough. check your oil every 500-1000 miles. you might have to add about .5 or 1 quart. depends on ur driving style.

see what i mean....personally I have never had a problem(knock on wood) but with everything I hear from ppl I may start changing my next oil change...Purolator?? Powerflow? (i work at sears so I can get those cheaper) I always used FRAM and everyone in my family has....I guess it was how I was brought up....haha

FRAM had a problem with their filters couple years ago. Defective Bypass valve design causing it to bypass "almost every day". meaning no oil ever gone thru the filter. Plus of the low quality material that they use, the filter itself actually ripped all apart, which means no filtering.

They redesigned their thing shortly after people "exposed" their design fault. Havent heard anything bad about them since.

I forgot to mention Mobil1 Filter, they have pretty good design, and I think they're only one that use some kind of Synthetic fiber filter in their filters.(most others use paper) they claim their filters can filter more crap than the rest of the people. their filter usually goes for 10-11 bux each. worth it or not its up to you. Check out Autozone, they almost always have some kind of Mobil1 deal.

well i have abut 2k more miles maybe ill shop around and see what else filters i can find because i mean fram is like 4 bucks i'm sure at autozone/advance auto etc i can get something that is better....

Autozone running a deal right now, u can get 5 quarts of mobil1 oil /w Mobil1 filter for 26.99 bux.

in case u want to go for this deal, the oil filter size for our engine is M108 (or M110, if u want a higher height filter)

Im thinking of going for this deal. couple months ago I "stock up" on the Castrol Syntec, I probably got like 5 dozens of that. but I'm down to 20 quarts now. cuz I have 4 cars for oil change. CX-7 takes 6 quarts, Altima 5, RX-8 4, Honda Fit 5.

Functionally, is there any difference between the M108 and M110?

an oil filter functions the same no matter what but a bigger one will always filter more hence being bigger so if i was to do that deal i would go with the tall/bigger one...could not hurt i'll have to check autozone out tomorrwo

If you change at 3000 miles, you need to buy 7 to 8 quarts. The oil change will take 4 quarts, then you will burn an additional 3 or 4 quarts until the next oil change. Figure 1 quart per 850 miles in hot climates.

if you burn 3 to 4 quarts between oil changes, you have a serious problem... :squint:

hmm... by the sounds of some of the 09 threads, they're burning a bit more oil than the older models... also, if you've got a custom map that tweaks the OMP rate, it's very feasible to burn 2-3 quarts in 3000-4000 miles.

yeah i agree if your burning 2 or 3 qts in an oil change u have a problem or a leak...i don't care how much you're beating on it you will not use that much if you would your motor cannot burn that much oil if it's being injected that fast.....

oh and his/girlfriend's car is an 05 i believe so even if the 09's are burning more then what does it matter his is an 05

if you do ultra high rpm for a really long time, say, Race? u can burn a quart of oil in as little as 100-200 miles.

but of course. most ppl wont do that.

and 09 naturally will burn more oil cuz it has an extra injector, re-adjusted OMP rate. they're trying to "shine" the "Rotary Engine brand name" you know.

good point... probably rules out a custom map too.

yeah and it's an auto so it can really b run at HIGH rpm those are limited in rev's to like 7 or 8k (correct me if i'm wrong it's somewhre there i think)

my rev limiter kicks in a heartbeat over 7500 ... and that's with an MM map. I wouldn't want to run my 4AT any higher than that anyway.

yeah that's what i though 7.5k is def not pushin near as much oil in as 9.3-9.5K

i find this thread useful..

beers :beer:

23000 miles can't be wrong. 1 quart in 1000 miles since the very beginning. Then after MSP16 it goes 1 quart in 850 miles. Done several cross country trips, and without the oil in the trunk I never would have made them successfully.

I changed exactly at 23000 miles this time and have 3 quarts 5w30 on standby. We will see how this goes and I will comment again at 26000 miles guaranteed. I will probably run out of oil and need to get a 4th quart of oil before the next change.

Well if it matters we use between 4-4.5qts running dynos for mazda reman, I just do 4.5 qts since thats what I was told to do there. As for filters as a Z owner I have always heard mobile 1 and k&n are the best but you also pay for it($10 each). Fram went down hill when walmart got there hands on selling them and I have heard wix is good but I never used them. Check the oil often though especially since this is your first oil change, its not bad that it burns oil just the way the motor is designed takes a little oil to keep her going, dont ignore a low oil light ever.

^this guy knows his stuff. haha he should since he works for mazda reman. Yea I typically fill abou 4-4.5 quarts. Mobil 1 oil filter when I can get my hands on it.

I have a 2010 Rx8 I'd say about 1 quart per 1200mi is the average over here in NC climate. I top her off every Sunday and check her pretty often. I also drive my car like I stole it.

I never did my oil change, but every time they always add 5 quarts of oil, because the receipt says 5 quarts all the time. At least a little bit more is better than very less...

This is genius

It is. Shall we nominate it for some sort of nefarious reward?

Does every forum have a monchie?

Thanks! :)


Please... :)


You betcha! :)


You got it! :)

Same here. The only time I changed oil myself it took a little under four quarts. But I must have done someting wrong for it to come out like that, so I've left it to the dealer ever since.

Ken

Adding oil in between oil changes, is one thing I do not miss.

Bump. What's the total capacity for a bone dry 4 port engine? I'm putting the top part of my new motor back together Sunday and would like to know.

Thanks :)
