Hello everyone, I just put an order in for a 2004 Chevrolet Express 3500 Cargo van and it will have the 300 hp Vortec 6000 V8 engine in it. [Smile] I will be using dino oil for the first 2 oil changes and i'll be switching to synthetic after that. I'll be doing a lot of miles (30k-40k/year)and want to assure myself i will get the most mileage out of this engine. What synthetic oil should I use for this engine? Thank you.

I would try Mobil 1 or GC, and do a UOA. If everything looks OK and there is no consumption, then I would stick with it. [Smile] There are many other good synthetics (amsoil, redline, RP, schaeffer's, etc), but I don't know what is available to you.

I have a 2000 GMC Sierra with the Vortec 5.3, similar to the Vortec 6.0. Due to concern for me extreme cold temps, I run Mobil 1 0W-30 in winter and Mobil 1 10W-30 in summer. This combination seems to work well for my truck. Average of 1 quart oil every 4,200 miles on the Mobil 1 0W-30, 1 quart every 6,800 miles on the Mobil 1 10W-30. I will also be trying the new Mobil 1 "Truck and SUV" 5W-40 this summer. Hope for better oil consumption and better engine protection. Jerry

Might want to check out Shell Rotella T 5w-40 Synthetic. I will be using it in my 1992 Mitsubishi 3000GT VR4 (twin turbo). I hear extremely good things about this oil.

I'm going to be recieving delivery of this truck in late March and I'm probably going to go with Delvac 1 or the Mobil 1 Truck & SUV. Are they the same?

Well Tommy, from what I've seen they "appear" to be the same oil. Delvac 1 5W-40 is badged for commercial use and indicates the appropriate HD diesel specs, including CI-4 and Cummins spec (I need CES 20078). The oil also is dual-certified to SL spec for gasoline service. In the U.S. the smallest container is a gallon jug, about 3.78 litre. In Canada, something like Wally World (Wal-Mart) carries it in 4 litre jugs. Mobil 1 Truck and SUV 5W-40 makes mention of "generic" HD diesel spec CI-4, and SL for gasoline motors. It comes in 1 quart bottles so that's a lot handier for a "small" truck. Ever try to fill a passenger truck or car with a 4 litre jug or, God Help You, a 20 litre pail?? Anyway, Mobil 1 Truck and SUV is mentioned in this forum and somebody was nice enough to post a high-res photo. It certainly looks like Delvac 1, since no other Mobil 1 product carries the CI-4 spec. Mobil 1 0W-40, rated B4-02, is designed for certain light-duty European diesel motors and some high-performance European gassers like Porsche and BMW. It's only rated CF so there is no current North American diesel motor you could use it in. Like I mentioned, although I use Mobil 1 10W-30 in summer, I do plan on using either Delvac 1 or Mobil 1 Truck and SUV starting in April. I have a couple of trips planned to Utah and Nevada in June and August, so that should give the oil a fine workout. Anybody have any thoughts on this?? Jerry
