ive not long done an oil change on my FRST with comma 5w 30 fully synthetic oil as recommended by my local tuner, im unsure because since my car has been smoking alot and oil smoking from the bottom of the turbo,

what is the best oil to use on a frst.

Thanks in advance.

10w 40 fully synthetic is best mate for rs turbos.A well known tuner told me this last week.He said 0w 40 blows turbos and mobile1 motorsport 15w 50 is too thin

 

Eh? 15w 50 is thicker than 10w 40!

 

5/30 is far to thin.

Ive never known a singke person have problems with mobil 1 motorsport.

 

right then oil change for mobil 1 15 w 50

thanks guys

 

Sorry meant too thick,ive always used mobile one motorsport but this question has been asked on the rs owners club website and everyone said 10w 40 so...................

 

10w40 semi synthetic is what powers use, thats what they told me to use...

although it has been said to use 15w50 as well
