maddie

 

You don't have a -SE. But I use 10W-40.

 

20W-50 for my FB!!

 

10W-40 Penzoil Half Synthetic now for 15,000 miles and no problems at all infact she runs better. March of 1978 RX-7 with 552,371 miles on the clock. Still original Engine.

No BS I have Docs to back myself up anytime anywhere.

 

^^^^DAMN thats a lot of miles for an original 12A!!!

 

Your climate will determine what viscosity oil you should run. Do you have the Owner's Manual, it states which oil to run in differing temerature ranges. The following table is from the 85 Owner's Manual.

 

552,371 HOLY FUKIN **** that is the best **** I have heared in I dont know how long. Thats great. WOW!

 

20W50 is fine year round if your in a mild climate.If it gets cold in the winter, its good to shift to 10W30.Gets your oil pressure up quicker in the morning.
Use non synthetic like Castrol,Valvoline or Chevron and change it every 3000 miles,religiously....best thing in the world you can do for a rotary.

 

Yo I know this is an old post but in case you're still on this site, mind me asking how you got it to run that long? Did you pre-mix, what kinda tricks did you use, any special tips for getting it to run that long? Thanks!

 

FIFTEEN YEARS, dude.

Seriously?!

Well if he only put 15,000 of those miles his statement means nothing.
