Oh, looks like you already had mine. But it's an S model. Your spreadsheet has it as a base, FYI.

***edit, I'm changing out the oil pan in the next couple weeks since I can't work, so I'll be scoping the bores, as the elevated levels of alum and iron had some suggesting bore scoring. ****

FYI there is no attachment or picture in your last post.



Thanks.

Here's mine. I'm not sure I would combine it with the rest as the right three UOA columns were taken as my engine slowly failed as a result of bore score. The left three columns are after the rebuild, but while the engine was breaking in again.

I'm only going to have one column per member in the aggregated summary, so just say which sample from that report you'd like me to include. Otherwise I'll assume the most recent...

Thanks.

It would be fascinating if there were enough samples to do a statistical analysis as to average wear metals per mile on various oils. I realize there are probably too many factors that could contribute, but it would still be interesting. I use Motul, but overall I don't see anything in the few samples here to indicate that it's any better than Mobil 1.

I'm not sure if I'm surprised or not. I've always trusted Mobil One although in the past I've been known to use Red Line.

134K miles on mine and I know all of the 5K mile changes starting at 35K miles have been Mobil One 0-40 European Blend. However, the last two changes each included a can of MoS2.

One thing I will note is that with each oil change pre MoS2 the filter would show a couple points that would sparkle in the sunlight. The two changes that had MoS2 had perfectly clean elements. I know that doesn't prove anything but I include it here in the interest of full disclosure.

That is very interesting.

Anyway...

Default Another oil analysis

Wayne - your oil is listed a M1 "European blend" - by that do you mean the M1 0W-40 "European Car Formula" or something else? I know my Mercedes dealer uses a Mobil 5W-40 they called "Mercedes Blend" so I realize there are lots of M1 blends out there that are not usually at the parts stores.
Thanks

Always good to clarify. Wal-Mart (no affiliation) home delivery (free) for under $25 a jug. I used to go to the box store (more expensive there than on line!!!) but they would often be out. On line delivery is generally a couple of days. I hate to shop so this makes it easy.

What differentiates Mobil 1 “European Car Formula” from other versions?

Slightly higher Zinc & Phosphorous levels

Interesting. I’m thinking about going back to Mobil 1 at my next oil change. It’s all I’ve ever used and at the last change I switched to Driven and my oil consumption immediately went up. If there is a Mobil 1 formula that has additives that the boutique oils have, that may be the way for me to go.
