Hello can I ask
Oil I am thinking of using 15-40. Semisynthetic
Is this ok
In my Renault 5 gtt

It'll be o.k. but there are better grades to use in my opinion. If it's just a road car then I'd use something like 10w40. If its used hard/on track I'd use either 10w50 or 10w60. :)

Tbh a good semi 10/40 would do unless your really pushing the engine.
