Engine oil for s1 11s

[steve111s]

Hi to all you Lads and lasses
Just a small question I would like to ask.
Could anyone out there in the Lotus Elise world
tell me what type of engine oil is best to go into
a S1 ELISE 111s W reg. I need a top up on the dipstick,
but I dont know what oil was used. So I might have to
change it. Any help would be greatly received.
Many thanks to all that give advise

I believe the manual reccomends 10W-40 so for just running around on the road a semi synth (which actually mean mineral and not synth at all!) like Castrol GTX Magnatec will be fine. If you want good stuff (highly reccomended if you are on going on track) post on Oilman's advice thread on general gassing and get a specific reccomendation.

Mixing types is not a problem, just make sure you're using a suitable grade.
