Engine oil !

[Richturbo899]

Hi this is really bugging me is 5w40 oil safe to use in a three cylinder polo 1.2 engine instead of 5w30 Volkswagen and handbook say use 5w30 is there any difference in oil ? and would it be a bad idea. Both are fully synthetic with the correct Volkswagen specification numbers

Thanks

Why do you not want to fill it with 5W30?

A lot of cars it says in the manual you can use a range of different oils, like when people used to run a 'winter oil'.

I'd always stick to the manufacturer's recommendation as per the handbook. Handbooks will specify permissible alternative grades (usually as 'OK for top ups') if there are such things. If there is no alternative listed in the book, I would assume it is not OK to use.

For the cost of the right oil versus the job it does, and the implications of getting it wrong, it's not worth the risk, IMO.

I've used baby oil with no untoward effects.






Edit: Oh, you mean in an engine.

Depending on where you look on the internet, 5w40 should be fine. Most of the engine oil finders I've looked at offered a range between 0w30 and 5w40 for the engine in your Polo.

I wouldn't have thought so, but 5W40 would be better suited to an engine that's got higher miles etc

If yours is high'ish miles, use it, you may find the engine runs quieter with it being that bit thicker, in the long ruine, it's not going to do any damage at all

Almost every BMW I've run is 5W30, but I run 5W40 due to age, miles etc... Zero issues, but a quieter and smoother engine

what a pointless clown reply. Well done you get +1 to your post count

I would suggest your post is even more pointless and a +1 to your post count, least mine highlighted the answer to the question he asked and answered himself.

Forgetting the pointless/useless posts from the goofy Timothy types on here, yes 5w40 is fine to use. It's down to a temperature range and 40weight oil is OK with the UK climate.

It should be just fine. Nothing to worry about and as others have said engine wear/higher miles may result a change in oil that can be used (thicker).
