Quote: Wonder if there is any antimony in this oil? Is there a new, Antimony-based anti-wear compound ? I'm a chemist, but not a tribologist, so I'm all ears. I'm planning to run this oil on the next oil change on my VW PD diesel. The "normal" OCI is 10k miles, but I'll pull a sample at 5k...

*shrug* FWIW, I'm currently running Gold GC 0W-30 in my 87 GN. I don't race it or even put many miles on it in a year, so I change oil by time rather than mileage. Prior to that, I was running Mobil 1 10W-30 "Green Cap". In both cases, I use the larger PF-52 filter. BTW, I was one of the...

I've used the DID 5W-40 for the last 4 changes in my 2006 TDI. I've never come across a bottle that had any type of citrus or other unusual smell. You made the right decision changing it out. Whatever was in that bottle wasn't DID. I hope it was actually engine oil. Many years ago, I bought a...

Yeah, Winston, I see that too. "Project Management" seems to to be the holy grail these days. To me, it's always just been something that one did in the normal course of engineering work. tigrpal, If your son is an ME see if he can get a summer job in a machine shop or some other way to get a...

What Patman said. I have a VW TDI also, and the filters are rated for 2 years/30 kKm. Thanks for the input, guys. Sounds like GC with a Delco PF-52 will work just fine for the 2 years/~2k mile OCI I'm anticipating. I'll probably pull a sample for UOA after that and see what shape the oil is in...

Group, I've previously used Mobil 1 10W-30 in my 1987 Buick GN with the 3.8 liter turbo motor. I don't race the car, and it's a "toy" so it only gets used about 1k miles per year (although when it's out, I make sure to get it well warmed up). The car is 90% stock and I change the oil about...

Or, just run some real TEL: Octane Supreme 130 For off road use only, of course. Rich

In the early 80s, I worked with a fellow who decided it would be a good idea to throw some waste Methylene Chloride in the gas tank of his Jeep. One rainy night I saw him pull out of the parking lot and there was this huge vapor trail coming from his tailpipe. From the smell of it, the solvent...
