10-40. 5-30. 5-40

What the hell are you on about you old fart????

Is that tyre related I take it?? Or the time you get up???

:hug: :hug:

:eek:
 
10w40 - more for diesels

5w30 - petrols for maximum economy

5w40 - petrols all engines

i wouldnt go "thicker" its either recommended or "thinner" oil and whether semi or full synthetic!
 
stick to 5w40 only!

thats why the 1*2's suffered from so many dephaser issues. Because people weren't servicing them often enough and using the wrong grade's of oil.
