VW 503.01 spec oil

[speedsix]

Alot of people recommend this for LCRs but it isn't listed in the book (500.00 502.00) Is this because it's a newer spec and wasn't around when the manuals were printed and is it ok for fixed service LCRs?

This thread has a list of all 503.01 oils..

I really think we need an oil faq stickied.

I was told the most up to date oils for LCR's is VW504.00/507.00

Something like
Castrol Edge 5w-30
Fuchs Titan GT1 5w-30 LLIII

http://www.opieoils.co.uk/performance_lubricants/ is a good site, gives recomendations as well.

I've never heard of those specs.

Isn't 0W30 too thin at 100c+ temps in regards to the 503.01 oils?

This is difficult to explain but, if for example your oil temp does not exceed 120degC at any time then a good "shear stable" sae 40 is perfectly capable of giving protection.

"Shear stability" is important here because if the oil shears it thins and that's not good!

However, if you are seeing temperatures in excess of 120degC due to mods and track use etc then there is a strong argument to using an sae 50 as it will have more viscosity at these excessive temperatures.

Maby with a remap you might need something thicker, I thought modern engines would be fine with it. not sure tho.

Think I'll stick with a 502.00 oil

Humm.......... So should i be worried that my dealer just put a load of Shell Helix 10W40 in my car at a 30,000 miles service ?

I personally think that 0w-30 is too thin for a tuned car. the last thing you want when your turbo is hot is a poor oil supply.

I Spoke to Opie oils and they said that 0w-30 (vw503) oil is ok for the TT and S3 but for a remapped car 5w-40 or 10w-40 would be better.

10w-40 was also recommended by Awesome GTi who did the work on my car

Ive just bought Motul 300V Chrono 10w-40 for my next service from opie oils, a bit pricey but worth it!!

does the 10w-40 need to be fully synthetic (spelling) on a mapped car

 

[cupra r rob]

Probably not but IMHO its best to use full on any car if you can. It reduces engine wear, inrease performance, fuel economy, better protection from cold etc

 

[beezasport]

i always use fully synthetic on my cars just wondered for reference...thank you
