Mobil 1. 10W30



Car seems to run MUCH smoother... Feels stronger... Is it just me? Or, is this **** the BOMB in a rotary?

they say no synthetic for the rotaries. they said if you put it in there the extreme heat that is produced by a rotary engine will turn it to a thick, liquid plastic kind of stuff that will eventually clog the ports and youll have to get the engine rebuilt. actually this whole thing is just made up but they do say that you shouldnt use syn

Well, I've researched it for 8 months now.. all the top tuners do it, and lots of people I know do it.. So I figured I'd try... I have 63k... So I guess if it hurts it, I'll just go BIG streetport and T51... https://www.nopistons.com/forums/pub...#>/biggrin.png

if it works out and you still have the same engine in a couple of changes let us know

See http://www.vtr.org/maintain/oil-overview.html for some interesting information about motoroils.



The value in using synthetics is that they resist degradation longer than conventional petroleum oils and allow you to extend your drain interval. If you use a conventional petroleum oil, and change it every 2,000 miles or less (assuming normal driving conditions), then I believe oil degradation is not a problem. Under those conditions conventional oil is every bit as good as synthetic and the overall cost is lower.

I started using Mobil one 15-50 synth about 6 months ago. It's awesome. Synth is all they use in Japan. I think were going to be ok synth is not going to hurt your car in anyway.

Most of the problems with synthetics were with the older ones that had alot of ash, which left deposits in the motor. Nowadays synthetics burn very cleanly, some even better than regular oil.

NO!!!!! Synthetics are made to handle much greater temperatures than mineral oils. They won't lose their viscosity the way that mineral oils do. Synthetics are also very good for turbos.
