Oil Question... Maybe a silly one...

[Jimbobcook]

Afternoon all,

Quick and possibly a stupid question...

I suggested a service to a local garage of mine for my FR and they were jolly happy about it but they said they would use the correct oil for the age of my car which would be 10w40 now I am pretty sure that every website I go to shows 5w30 as the oil for my car...

I questioned the garage to why they would do that and they said as your engine is worn in 5+ years old they tend to put in 10w40 as it's better for the insides etc blah bah blah

Now I have done a bit of googling and haven't found much on the subject for the Leon that really gives me a definitive answer...

All I found is that people think that 10w40 should not be used in below 0 degrees centigrade as it thickens and takes longer to be pushed around... now just going into Winter in sunny England we are probably going to be having plenty of 0 or less in the next few months...

Any ideas on the matter? Is this guy speaking bollocks or is there a shred of truth to it...?

Cheers

10w-40 is good for -20 degrees centegrade to +40 degrees.
5w-30 is good for -30 degrees centegrade to +25 roughly.
So if I think these 2 to compare I would choose the 10w-40 For English weather because I think it rarely gets below -20 over there.

I think the maintenance guy correct on this matter. Also for the 10w-40 is a bit thicker your car might not eat it so much, as Seats, wv, audi etc motors tend to.


Heres a quick link for comparing oil types according to temperature needs.

Well I have learnt something today

Thanks again

Yes it would have nothing to do with the fact most garages have a 50 gallon drum or two off 10/40 oil sitting in the corner of the workshop that they like to stick in anything that moves
Saves us having lots of little used expensive oils sitting around on the offchance
Its ok for most cars and even if its not , we'll think of a good argument that makes it ok
