High Mileage Oil??
Hi, I am not sure which oil to use. I keep hearing different things. 10w 30,
10w 40, 20w 50??? Which is best for the rotary engine, I have about 126,000 miles on it. Would you recommend the "High Mileage Oil". Just looking for the best oil to use. Thanks

Ive always used Castrol GTX 20W50 also.
The way I look at it is like this...when its a warmer climate, use thicker oil, as oil thins as it's heated. If the climate is colder, use thinner oil, as it will not thin out as much.
Thats how I always thought about it, but maybe my thinking is completely flawed! LoL. I dont know. That's why Ive always used 20w50, as it covers all the temp ranges. Plus the fact that it is what my dad always used in his

All "Mobil 1" oils are fully synthetic.
10W-40 is crap, never use it in anything
10W-30 is good for RX-7s in all climates
20W-50 is good for RX-7s in warm climates
Mineral (dino) oil changed regularly (3000 miles or less) with a good filter (not Fram -- use Mazda, Purolator, AC Delco, etc.) is appropriate for all but the most extreme uses (racing on tracks).
There are some other good choices, too, but the ones listed above will be fine.

I don't know for sure, but I'd avoid the high mileage oil because it's formulated to resist burning and our engines inject oil into the combustion chamber to lubricate and burn.

ah, so that's what that high mileage stuff does...
There's no need to debate synthetic vs. non-synthetic here 'cause there are plenty of threads on that, probably even an answer in the FAQ (sticky at top).
