OEM Mazda or Mobil 1. I personally run the Mobil 1 filter.



I also run the Mobil 1 synthetic oil. A lot of ill-informed people around here will tell you not to do it because of the OMP, but theyre beind the times. A lot of gains have been made in the field of synthetic oils and now theyll burn cleaner than conventional oils.

Oil injected into the combustion chamber is going to burn...

End of story.



People always say not to run synthetic because it doesnt burn as clean and will leave more deposits. Fact is, synthetics burn cleaner now.

synthetics don't have the imperfections that dinosaur oil does and therefore does not make the oil control seals swell to fill the void that wear causes.



I use castrol gtx 20w-50 in my turbo, and 10w-30 in my n/a.



I also use a 1973 rx3 oil filter that is twice the size of the stock filter.



If you want to be good to your engine, just change your oil more frequently. I used dinosaur oil in my turbo and changed it every 2000 miles and it lasted running strong for 215k miles.

just change it, no need for synthetics



I did run Mobil 1 in my 1985 RX-7 GS for 3 years that I had it, and I beat the hell out of the car and never had a problem, but I wasnt

paying for the oil so I figured why not?

I Use the K&N oil filter and run mobile 1 synth. The car runs better than ever. But an oil leak seemes to be coming from the oil preassue sender or the oil filter pedestal and is throwing the **** all over the place. A quart evert 2-3 weeks is getting kinda expensive. Damn oil leak.



To not post another topic, Can any one offer me any help on what is causig an oil leak big enough to go all the way to the middle of the car.
