Between the Formula M ESP 5w40 and the VAG-spec 5w30, I would go with the 5w40 if I had a common-rail TDI engine.
Thanks !!! =)

Thanks for the response. I guess Volkswagen's 15k km service interval is as stupid as it sounds, given the way it dumps fuel in there for regens. Good advice, I will flush at 5 or even sooner and run the next batch for 10 and take another sample.Todd,
With 28,000 miles when this sample was taken, you'd still be seeing some break in wear. Still , the levels of Fe/Al/Cu are elevated. I think the culprit here is the VERY low viscosity - 8.6 Cst at 100C is in the 20wt range. These VW 507.00 oils usually test out as a borderline 30/40 weight. The measured fuel dilution of 1.0% (if accurate) isn't enough to cause this big a drop in viscosity. I'd almost bet there's more fuel than that...
I'd do a short run of 5000 km to flush out the engine, then change the oil and filter again. Run this oil for 10,000 km and retest. If things aren't back to normal you may have a problem here.

Thanks for the response, TooSlick. I'm a little afraid to check the camshaft, but I'll be pulling the VC before my timing belt so I can have the R&R done at the same time if necessary.Cakins,
The only way to really tell is to pull the valve cover gasket and do a physical inspection. I've literally reviewed hundreds of TDI analyses over the past fifteen years and my impression is that all the API/CJ-4 synthetics are performing very well. Most if not all are using roughly equal amounts of Mg and Ca, as detergent/dispersant additives. This allows you to get a TBN > 10.0 while still holding to the 1.0% sulfated ash limit that's part of the spec.

Engine oil that is doing its job holds soot in suspension, instead of allowing it to settle or collect in narrow passages. Oil that is not black is probably not doing its job.Any insight as to why my oil is so black so quick is greatly appreciated! Also, I had planned to do 10k mile oil change intervals with the Shell Rotella T6, but now wonder if I should change sooner since it's so dark so soon.
Thanks.Turbo van,
If you're using alternate fuels like WVO or B100 I'd employ used oil analysis testing to determine optimum service intervals. If you're using up to a B20 blend you can use established service intervals of 10,000 miles/1 year.

Well, if it's any consolation I have not read in any forum including this one that Mobil1 ESP has led to early turbo failure. I would not shun the oil if I was you. Mobil1 makes a very fine product as do many others. I would just get two more liters of Mobil1 ESP and use it up then switch to another brand if you so desire. No science here just my thoughts. If Mobil1 ESP led to early turbo failure I'm sure someone would have raised a red flag by now.I've had good test results (OA) while using Castrol's LL03. It's been in the car from mile 1 to 130K miles. I decided to switch to Mobil 1 ESP at the 130K mark. Roughly 137K miles now. I had an unfortunate turbo failure last week. Car is still being worked on. Could be completely coincidental, but....
Does anyone have any first hand knowledge on used oil tests between these two oils? I've heard good things about Mobil 1 ESP and I use Mobil Full Synth in my wife's Honda. I know guys that are satisfied using other brands of 507 spec oil. I'm leaning toward going back to Castrol. I have two full bottles of Mobil leftover. What about mixing the two at the next oil change? I don't have any other use for this type of oil and would hate to throw it out.
It should not be a problem, Blackstone lab explains this on their website...When you guys go into the post office to mail out your completed kit and they ask if there's any liquids in it, do you lie? Or tell them is oil? I've been told that if you say its oil, it will cost you like $30 to mail it in the continental US...
Score!! Found it (the letter stating its 100% OK to ship) printed it shipping it later!!! Thanks!!!It should not be a problem, Blackstone lab explains this on their website...
You will have no problem with the post office. It's like 3 bucks to send it.When you guys go into the post office to mail out your completed kit and they ask if there's any liquids in it, do you lie?
