Hey guys, just out of curiosity what type of engine oil do you use on your 7's? Brand/ Viscosity ya know.


And also do you guys believe in any of that fuel treatment to "clean your fuel injectors?"

Also have you guys seen those "super coolant" additivies that make the coolant much cooler? Any Luck with that? Thought it might be a good idea to use that on our cars since they overheat so much eh?


And yeah... treatment stuff in general? Yay or nay for 7's?

Thanks!

 

twice?

 

I run Marvel Mystory oil in the gas to lubrate and clean the fuel system, seemed to solve my cold flooding problems. As for oil I use Castrol GTX.

 

Just use a clean burning oil and, I agree with using MMO, but not Castrol. Castrol is a mix of left over oil from other companies. Mobil 1 has been around for a while... if that says anything. Refer to your viscosity ratings depending on your ambient temps. As far as coolant- just use a 50/50 mix(again depending on temp) and make sure cooling system is functioning properly.
