Some advice needed guys,
I've acquired 5 litres of Mobil 1 Rally Formula 4 stroke 15/50W engine oil, Problem is that it's oil designed for motorbike engines. Could this type of oil be used in a 4 stroke car engine? possibly turboed multivalve versions.
It was all free so if i can use it, Great.
Thanks!

 

I wouldnt thats some thick oil there. Only use i can see for it is in a classic car tbh

 

Wasn't this same grade as the Mobil 1 Motorsport that was a common oil for by engines. New one is 10w60 I think

 

Motorsport's never been that thick mate.

 

Mobil 1 Motorsport was 15/50 for years

 

Was it really ? I used it for donkeys and never recalled it being that thick....it went down to pisswater at one stage and I stopped using it because it was too thin

 

mobil 1 was 5/50 and was really for modern 16v motors. if you warm the engine up before revving its nuts off it shouldn,t be a problem.

 

That's what I thought....

 

Mobil 1 Motorsport was indeed 15/50 as I still have half a tub of it here

 

Yes it was 15/50!!

 

Yep, That's the grade, 15/50 fully sinthetic 4 stroke bike racing engine oil, Classic 1 litre grey bottles and they even have that small square thing with lots of small dots that are for readingnfo using your iphone so i don't think that these cans are all that old.
The original question remains though, Could this particular oil be used in a turboed 16v car engine without issues??
The viscosity rating is the same as the original turbo 16v engine, 15/50W.
Let me know.
Cheers.

 

5/50 when it first appeared would post a piccy up but technology not a strong point put it into a x flow or pinto and it would leak as it was that thin a viscosity. lots of grades available under the mobil 1 tag nowadays
