garage used different oil
hi guys,
local garage did an oil change last week for me, they refilled with 5w40 instead of the usual 10w40 - - does this matter?

Re: garage used different oil
It can make a difference - thats a thinner oil than what is recommended for the engine. I'd get them to change it back to the proper as they haven't done a proper job!

Hi Alex,
Thanks for the reply - have spoken with the garage and they say they have a database system that tells them exactly what they can use... They are double checking this for me... in the meantime I spoke to VW and they say it's fine to put 5w40 in the engine - i'm confused now!!

Re: garage used different oil
Nothing wrong with using a 5w40 oil instead of 10w40 all it means is the oil has the characteristics of a lighter grade when cold (at start up) but is the same as a 40 grade when hot.

Re: garage used different oil
I had the same problem at my mates garage the other day but he used 10w40 on my GTI which gave me an oil check light we then changed it for 5w40 and its running perfect now!!
Re: garage used different oil
good-o - reassuring to know everything is okay then - so really it's an improvement over 10w40 that i've been using previously?

Re: garage used different oil
The engine should have 10w40 in it as per factory spec, but a 5w40 can be used if its put in. You can even run fully synth 0w30 in the engine if you like, but not many do it as its expensive!
Surprising the 10w40 gave you an oil check light - you sure it wasnt a filter problem at all?

Re: garage used different oil
VW spec for the engine is 10W40 - just checked ETKA
Re: garage used different oil
Im no expert on this subject but I spend hours researching the best oil to run in my 6n2 GTI.
The first number 0w or 5w, just tells you what thickness the oil will have when the engine is cold, 0w or 5w is perfect for UK temperatures, especially now its winter. Basically the higher the number, the thicker the oil, which means it takes longer to reach vital parts of the engine when you start it from cold!
The second number 30, 40 etc tells you how thick the oil is when the engine reaches temp. Which one you go for totally depends on your driving style. If you have your GTI in the higher revs frequently, 30 is better because it can flow better when the engine is at high speeds, therefore better protection and less resistance on the engine, so slightly better engine response.. 40 is better is you change gear early as it protects parts sligthly better, but also has more resistance on engine as it is thicker, No biggie if your changing gear early.
I run 0w 30, because I want my engine protected the min the key is turned. (Thin oil when cold, and when I drive hard in the summer, I want better protection in higher revs!) Im using castrol EDGE. Expensive but fantastic oil.
As long as it meets VW 503.00 spec, VW are happy for you to use it in your engine.
0w40
0w30
5w40 all support this spec!
Hope this helps guys..
