If it's for 4-stroke bike engines, the oil will have a slightly different mix of additives compared with the "car" oil.

It's likely there will be less friction-modifying additive in the 4T. This is because the oil in bike engines lubes the gearbox & clutch as well as the engine, and too much friction-modifier can contribute to clutch slip.

However bike oils have more anti-wear and scuffing additive, because they run higher compression, higher rpm and higher specific power output.

I would suggest trying to get an alternative car oil, I'm sure the bike oil will do the job very well but Scoobs can be fussy about oil

Hi

You are exactly right about the friction and wear additives. Can you recommend a different Mobil oil?

Is Mobil 1 4T racing(15w50, API SJ) the same oil as Mobil 1 motorsport 15w50?

The local Mobil rep says that Mobil 1 4T has replaced Mobil 1 Motorsport. Is this true?

The container for Mobil 1 4T racing states 'fully synthetic oil for motorcycle engines'.

What do I do?

Edited to say Mobil 4T racing not 4R
