Euro Oils Timing Chain Protection ?

[ChrisD46]

Do current Euro oils have the same level of timing chain protection (or better) as do SP / D1 Gen 3 domestic oils call out ?

They should not be worse, and likely better.

When looking at two oils of the same viscosity grade yes. A standard pcmo 20 and pcmo 30 won't protect as well as euro 20 and euro 30.

D1g3 oils have no minimum hths for 20 and 30 grade. I suppose the thinnest euro rated 20 which has a minimum viscosity of at >2.6 hths may protect slightly less than a thick d1 g3 5w30 with 3.1-2 hths but that wouldn't be a realistic expectation one could have.

Additionally, if comparing xW-20, LSAC/API/dexos oils to Euro approved (VW508.00 etc.) oils, you'll find both have very similar HTHS. Unlike comparing 5W30 where the HTHS of the Euro is significantly more than that of the ILSAC. However, even in the Euro approved xW20, the chemistry may be more robust.

The only ACEA standards that require the GDI timing chain test are C6, C7, and A7/B7.

The Mercedes standards have some tests that measure timing chain wear, but they aren't very relevant to the GDI timing chain issues.

Great question. Being that the euro TGDI engines tested are different and the testing protocols are probably different I don't know if we can draw any parallels between them. Thankfully almost all euro oils sold today meet the "performance requirements" of SP so the point is rather moot.

A thicker oil may be better for timing chain wear in general (or it may not, haven't seen any evidence of this). The test in API SP is specific to problems with chains in GDI engines caused by soot. Viscosity isn't relevant to this type of wear. It's all about the additive package.

D1g3 oils have no minimum hths for 20 and 30 grade.

They'll have the same minimum HTHS as API SP.

Euro automakers test on their own TGDI engines so it's hard to say.

Somewhat on the subject. If in doubt go thick.

I think they do, but I cannot prove it. LOL
Seriously, look at the specs of the Oil you want to use, there are many players out there:
1) Amsoil
2) Mobil 1
3) Redline
4) Valvoline
5) HPL
6) Shell/Pennzoil

Look at all the Data you can gather and then make your Decision.

They do. BMW has a specific timing chain test conducted on N20/26 engines that had issues with it. All LL approvals are subject to that test.

This is currently the test for API SP

Pass/Fail Criteria• The pass/fail criteria is ≤0.085% timing chain elongation.
