What is the thickest oil I can use in my Corsa C 1.0ltr 2001 ?

The manual says 5/40.. When I buy, they ask for the reg No then give me 10/40.

I do a lot of motorway driving and want the engine to last.
Its done 70,000 and has been looked after, but does need topping up once a month (no leaks) so should I use a thicker oil?

There is a bit of cam noise when hot, but otherwise it's in good shape (and I want to keep it like that)

The oil I buy just seems so thin

Any help appreciated Thank you

The manual recommends 5/30 but I use 10/40 because of the age of the car.

thicker oil should quieten it down a bit

That's what I thought. So 10/40 is the thickest stuff that is suitable for that engine is it?

Thanks for advice

10/40 will be fine, pretty much any Vauxhall small block will live forever on 10/40 as will 90% of petrol engines

10w40 is the one :thumbs_up:

As said above 10W-40 is fine.

When hot 5W-40 and 10W-40 are the same.

If you want the engine to last the key thing is to use good quality semi-synthetic oil and change the oil and filter every 5k. Also, drive the engine gently until it has reached full operating temperature.

I do know a bit about oil...now retired my dad was a research chemist for Burmah Castrol.....

although not cheap 5w 30 magnatec is the finest synthetic motor oil in the world...so good you could almost fry chips in it.

When at castrol he used to say it was about finding the right car for their oil not the other way round ! and magnatec was too good for Cars.

Thicker oil wont give you start up protection which is when you need it most...not while motorway driving..magnatec affords optimum protection under all conditions and castrol have spent more developing it than GN have developing the corsa !
