hi guys whats the best of the cheeper oils that i should put in my 3.9 v8 classic when i i do a engine oil change or do i have to go with the expencive one and should i use 15w/40 or a diff grade many thanks simon
Can use 20/50, don't use synthetic just ordinary mineral multigrade. Ideally Valvoline but any decent make. Regular oil & filter changes are the secret.
