1985 GSL-SE - preferred motor oil
I haven't been on the website for quite some time so please feel free to flame me for the noob question. I have 122,400 miles on my 13B RX7, which I bought from the original owner almost 8 years ago. Initially I used 10W40 oil. Then a few years ago I bought a case of Castrol GTW 10W30 at Costco and used that. My last oil change was with Quaker State 10W30.
What is the preferred motor oil and weight of members for this engine? I understand that the engine would not benefit from a switch to a full synthetic oil, is that correct?
Lastly, would the engine benefit from using any fuel additives, eg. Chevron Techron. I have never used any fuel or oil additives since I've owned the car.
Thanks

Well I strongly suspect the 20W50 influences your lower oil consumption as its a much heavier oil. It strikes me that is too heavy an oil for a 13B motor.

Remember that these are very hot(internally running engines) and you need a weight of oil that will lubricate at higher temps.

10W-40.
My preference would be to perform the 2-cycle oil mod to the OMP, and run synthetic for the internals. That route sounds like the best of all worlds to me.

10w30... The shorter the range, the less viscosity enhancers, and hence more oil is in that quart.
To stabalize it over a broader range, they add more "non-oil" chemicals to it.

I use 20W-50 in my 12a w/193K on it. The brand is one few have heard of, but it is approved for use in airplanes, so it must be good. Even carries the military spec for aviation approval.
