A big difference - no - unless you had lab facilities to do teardowns and measurements .
Real world answer is no .

My point exactly........

Question: "Trying something different"....do you really think its going to make a significant difference?

Using a 0w oil in Texas!...I could understand it if you lived in a climate with winter temps in the sub-zero area...but Texas???


Actually, That's why I'm asking...Because if it won't make difference using the 0W40 then that will be nice because it will be another oil for us to choose from because as I said in my post "We have been using the valvoline 5W40 since new but the 0W40 is the only other VW 502 oil we can find and it's also more readily available than what we are currently using"!!!

In another post I said "That store closes early so it's hard for me to make it there in time....Just looking for some other options because the M1 0W40 seems to be everywhere..."


On one hand you're making it out like it's absurd for someone to want to use an oil that's easier for them to get and on the other you're suggesting it won't make a significant difference...
 
Use the M1 oil. 0w or 5w, who cares? It won't make a difference at any temp you're likely to see in TX. It is a VW 502 approved oil, among many other approvals.

Yup. A Euro 5w40 and Euro 0w40 should have the same/similar visco down to freezing, maybe even to zero, or even to -20*F.

Which is why we are running M1 ESP 5w30, which carries VW 504/507, which supercede the 502 specs. UOA results coming!


VW 502 is a very current oil specification.
VW 504/507 is a more recently introduced oils specification.
Oils that meet 502 specs have too high a content of Zn and other ash forming substances and therefore cannot meet VW 504/507 specs.
Some applications/emission requirements call for VW 504/507 some don't.
Sort of more like BMW LL01/LL04 than API SM/SL.

502.00 is about 10 years old.

Every 504.00 oil I have seen is recommended for 502.00 applications too. (others than just Mobil say the same thing regarding 504.00 and 502.00)

I've just changed it....I was finally able to get to the store before its 6 p.m. closing time and got some Valvoline 5W40...Had almost a full quart of Mobil 0W40 that I used as a top up oil and mixed it in with the Valvoline..I'll probably go with the 0W40 next time because it's a little cheaper and easier for me to get 24-7 at the local walmart.

FWIW, I was at the dealer yesterday getting a part and my wife handed me a brochure from VW on using the right oil. It stated 502 for gas and 507 for diesels.

It is true that many of the 504 oils state they're good for 502. I guess the question is whether they are as robust as 502 oils that are not 504 rated. Certainly on paper they seem to look weaker, at least to my untrained eye!

Yes 502 is older but still current. True 504 can be used ( vs recommended) when 502 is required but not the other way around. For example : Mobil 1 0W-40 ( a very current oil ) is 502 but not 504 compliant due to its high Ash content. Mobil 1 ESP is especially designed for Diesel Particulate Filters.
Different oils for different uses. Sure you could use low Ash in an engine that does not need it...but why would you ? Buyer beware?

Exactly.

Not to say you shouldn't, but there's no positive reason unless the low ash oil is demonstrably superior in some other way that is important to you.
