Engine Oil

[AlleyCat]

Hello all,

I currently use Mobil 1 15w50 motorsport, but as this is discontinued, i was looking at using the replacement Mobil 1 10w60 motorsport oil. however im not sure if i can? or if this will have some adverse effect.

the engine its going in is a supercharged A series, that produces 140bhp. so its quite high output.

any advice as to wheather i should go ahead? or find a different oil?


thanks

Maybe you're forgetting that that dear little engine was designed in the 1950's, not only that the oil must also lubricate the gearbox. I do believe good old 20/50 is plenty good enough and about as thin as you need to go, supercharged or not.

I'd agree with the above, some classic engines benefit from modern oils (the triumph 1500 being one) but the A series has enough difficulty keeping the oil in using thinner based oil is asking for problems.

Good quality 20/50 will do you fine.
That said if your running it through a cold winter and not doing a few long runs but doing lots of short runs a change to 10/40 will not harm it for the winter.

Pretty much the best oil you can buy for a classic Mini is Millers CTV. This is a semi-synthetic 20W50 that has additives for the gearbox. However, it's not cheap.
