Synthetic Group 4 Oils

[Joe_Black]

Mobil-1 has consistently been a Group 4 synthetic and actually got into a major legal battle due to Castrol's efforts to reclassify Group 3 base stocks as "synthetic" for advertising purposes. After Castrol was successful, allowing them to legally market their blended oil (Syntec) as a pure synthetic to the largely ignorant public, there was a great deal of concern Mobil would start using Group 3 base stocks in Mobil-1 as a "profitable response". Apparently this never actually materialized, and the various MSDS information and engineering data that I've been able to review for the Mobil-1 products that I use (vehicular and commercial) have borne this out.

With the purchase of the new VW Jetta TDI a new twist came into my lubricant maintenance in the form of VW's specifications for the TDI engine. Come to find out there isn't any domestically available oils that fully meet the specs, so I ended up special ordering the manufacturer-specified Mobil-1 product from Europe via the http://www.avlube.com/ web site. The packaging bears a striking resemblance to the Mobil-1 Extended Performance product. Fortunately the cost is comparable to buying the regular Mobil-1 locally, so I get to stay in warranty without going bankrupt.

I've been accused many times of being a Mobil-1 representative but base my assessment of their products from real-world applications. They've got more exposure in industrial, commercial and agricultural applications than any other synthetic lubricant. And when it comes to multi-million dollar operations, where equipment failures mean $$$ per hour downtimes, you don't buy your lubricants based on popularity. Period.

Hey Joe,
Good info to know. I love to research so i'll keep researching this stuff. I did access the website you mentioned and it looks interesting. I know the new Syntec "europeon formula" oil shows "made in Germany" and not the USA so i hope it's not false advertising. They're claiming the 'made in Germany' syrup is Group IV and everything else labeled syntec is Group III. Who knows?
All i know is i'll keep changing oil religiously.
Speaking of oils, what about filters? I'm using the Mobil l filter. Again, i tried to do my research.

I was about to recheck this same topic before my oil change this weekend.
I use Mobile 1 and thought about switching to something else.

There are a few sites out there where people have gone out and bought a bunch of brands of filters and cut them open, then rated them on things like bypass valve quality and filter element area. The Mobil-1 does well most of the time, so it's a safe bet. IIRC, Fram always comes in near the bottom. I've been running Purolator for a long time and am always happy with how long my oil stays looking cleaner. Before that, I only ran AC/Delco filters and was always happy. The VX and Subaru have only had Purolators or Mobil-1 filters.

This is one is motorcycle filters, but you get the idea:

K&N filters. When I drop the Mobil1 after 3000...it looks like maple syrup. Nice and clean. In the Lightning truck as well...80000 mi. and same deal, still changes out clean.

I at the time of the first oil change they told me that I had run a quart and a half out of it. I have now put two quarts into it between changes, so I have to start looking into some solutions.

I want to start the synthetic, I don't know if that is an option where I take it now, but if not, I'll have to change places. Will that help the burning issue? I am going to go back into the arch's and see what has been said before, I know it's been covered, and see what that does for me.

For me, my oil endeavor begins.

I like the Mobil-1 filter because it's fully synthetic and doesn't have any paper or cotton-gin inside, and not specifically because it's branded by Mobil-1 but that it's less expensive and easier to get than the equivalent fully-synthetic Wix filter. Here's an interesting site where someone takes a fairly objective view of a wide variety of filter brands by disassembling many popular brands and determining who makes what for whom: http://people.msoe.edu/~yoderw/oilfi...lterstudy.html

For my diesel tractors, military and commercial trucks I pretty much use Wix or NAPA, and sometimes Caterpillar for my Caterpillar dozers. The Mercedes diesels always get Wix synthetic on both the oil and fuel filters.

The VX and Subaru have only had Purolators or Mobil-1 filters.

those are what I run too!

I'm thinking that if you change your oil at 3,000 miles or less, it probably doesn't matter much which synthetic you use since they're designed for long-range travel and abuse. I favor the Mobil 1 filter since it seems to outperform even the K&N synthetic filter by a good margin as far as keeping 'ugly particles' out. I have seen the website where they 'tear apart' oil filters and diagnose very closely too. Anyway, at this point, i'm still
with 0w30 Castrol "Europeon Formula" synthetic oil with the "made in Germany" notation on the bottle.
My VX doesn't use any oil whatsoever between changes so that makes me happy as well. I also use it in my '04 Dodge Ram 5.7 truck and my '90 Allante' with the Mobil 1 filter and am quite pleased.
Let's keep researching.........'til the end of time.
