Ive seen on several sites that you shouldnt run certain synthetics in a rotary engine. However I was cosidering running Mobil one. Has anyone here been succesful in using mobil 1 sythentic engine oil.

 

yes you can use it if you can afford it. still suggest changing it often to prevent dirt buildup.

 

Mobil 1 is not as expensive as redline or neo.

I use Mobil1 ...it's under 3/qt at Target..cheapest place I have seen it.

 

Then what do people say to not use synthetics? Keep this car super expensive to maintain or something?! Man how ghetto-fab is that.

 

I've been using Mobil1 as well for over a year. 15w50 in the hot texas summers and 10w30 in the winter. As per my power fc commander, engine temps under all conditions dropped ~5 degrees C (9 F) and the car revs noticeably smoother. Turbos seem to spool quicker too

 

I have been using Mobil 1 with no ill effects thus far.

 

its expensive in regards to the fact that you have to change oil more often than a regular car. you have to change oil so often that its more economically feasible to use regular. having said that full synthetic is still the way to go imo.

 

Not to mention oil tempatures return to normal much faster after a hard run. CJ

BTW, i do use 15-50W

 

Mobil 1 15w-50....FDs love it

I use the new fram oversized high effeciency oil filters ("X2") and the oil still looks pretty good at 3k miles (which is when I change it), and I'm on the boost ALOT

 

Mobil 1 OIL FILTERS....

ill try the mobile 1 oil in about 2K miles*next oil change

 

I thought that the aftermarket filters were no good. I recall reading that it is safer to use Mazda oil filter. Is that true?

 

Mmmmm... A trunk full of goodness in my usual 56k-friendly thumbnail.

I can't seem to find the Fram or the Bosch high-performance oil filters. Where do you get these? I haven't checked everywhere, but I've tried the major auto stores.

I just use the Mobil 1 Reg. Is the synthetic worth it?

 

As I said b4 so many time, all Japanese Rotary speciality shop have their own full syn oil. So Full syn is safe for rotary. Mobil 1 is the best mass production syn oil out there. It may not be as good as redline and neo. But it will do the job.

 

Mobil 1 is all I use in my rx-7 and I still change it every 2000-2500 miles. I use the purolator filters designed for 2nd gen rx-7s as they are larger. Stay away from fram. They are very cheeply constructed with paper endcaps on the inside.

Factory manual for the FD says not to use synthetic

have you seen the X2? it is sweet http://www.framx2.com/

it should be, for 10 bucks

 

Thanks for all the info ive just started using mobil1 10W30 i guess ill withch to 15W 50 next oil change

P.S. I am using a fram oil filter. Anyone have any comments on that.

 

Fram oil filters were good at one time, but that was at least 6 years ago.

I use the Purolator Pure 1 filter in all my vehicles, including my John Deere lawn tractor.

It just so happens that my motorcycle and 3rd Gen use the same size. So, I buy four at a time when they are on sale at Advance auto.

I believe the part is PL14459

It is larger than the stock 3rd Gen filter, but it fits. I've been using them for about 18 months now, no problems.

I also have been using Mobil 1 15/50 for about 12 months now, no problems.

 

It also says to leave the stock AST and stock pre-cat on

 

If you replace youre oil every 2K or less it makes sense to use dino juice if you go longer between oil changes synthetics might be worth it.But beware the added expenses of synthetics dosent mean longer engine life on a FD, when the dreaded o-ring failer strikes it dosent matter what oil you are using.I say save youre money and upgrade youre cooling system this will help youre motor live longer.

 

I'm with you. Remember those commercials where they have synthetic in a hot frying pan and nothing happens to it? I figure it's more resistant to burning than regular dino juice and could coat the combustion chamber and clog the cat over time. If you're changing every 3,000 miles anyway, why take the chance?

 

Where do you guys buy the Fram X2? Please, I don't want to use the stock filter!
