What's the best oil to use in a '93 rx-7....synthetic or regular? I have heard conflicting things about using synthetic. And what is the best weight?

 

I use regular with mine, I use a heavier oil in hotter weather , like now i use 20-50 in the summer, dont really drive my car in the winter so i dont have to worry about the colder weather.. but you should try doing a search.. im sure there are a ton of threads on this subject

 

Check threads, you'll find a great deal of controversy
concerning motor oils.
I say 10/30 winter-20/50 summer no synthetics.
Took this off the net:
Cameron Worth, President and Racer-Tuner of Pettit Racing and Excellence PerformanceCorp. suggested that I use Valvoline 20-50 Motor Oil in the engine.
Use a good quality oil and keep it changed.

 

Wow it has been like 2 whole days!

I'm not reading the forum as much anymore, the topic repetition is making it a waste of time.
If there are so many people that cannot even figure out how to do a search I fear there will a lot fewer FDs in the coming years.
If they are stunned by something so simple I can't see how they will be able to maintain these things.

Don't be an ***! I am in software support and I know how to search. Sometimes it is just better to get to know people on the board and it can be faster to just ask straight out. You should have more pride about people wanting to ask you for help and your opinion. If you don't want to give it, start your own site tech boy.

 

Sorry....I forgot to thank the first two guys...I appreciate the info.

 

Kind of thin skinned for support aren't you?
What software are you supporting?
