what up,

My friend just got a '93 rx7 TT. Well after about a month in the shop because for some reason when he hit a pot hole the tire went through the splashgaurd and burned up the wire harness...he finally got it back. My question is, tomorrow we are gonna change the oil so I was wondering what is the recommended weight/viscosity oil to use? Someone told him to use the lightest oil like 5w-20, but I did some searching on this board and I see people using 20w-50 which is a big difference. Also, whats the best brand of oil filter to use? Thanks.

Use a good 20/50 like Castrol or a good synthetic like Redline, Mobil 1, Royal Purple, etc....

 

i use catrol gtx 20w 50 with either stock or mobil 1 filters...no complaints yet

 

20w 50 in dynosaur and mobil 1?

 

I use Havoline. 20w50 in the summer, 10w30 in the winter. I would go synthetic, but with all the free Havoline I want, I'll stick with dino juice.

 

Yes, but do you keep the same weight , whether its synth. or dino.? I'm swithing to mobil 1, just not sure if I'm suppose to change weights or not.

 

A lot of people are using 15w50 synthetic oil.
