I break all my motorized vehicles in that way.
Coils? If you mean glow plugs, if you're quick, you'll see the glow plug light on the dash for about 1 second on the first start of the day. Otherwise, it doesn't light up. As for oil, I changed the oil on my Colorado HD at 3000 miles. I have 5100 on it now. The oil filter life showed 64%. It is not measuring dirt accumulation, just miles. I bought my filter with cap from idparts. They sell the filter element without the cap as well. I did not see any reference to a 5000 mile change in the manuals but to be fair, I may have skimmed over some of the manual. The service schedule shows changes at 7500. The highest trans temp I have seen on mine has been 192. That was on a 98 degree day here in Florida. I had driven home from work 62 miles. Otherwise, the average temp I see (and I check once a drive) is about 175. That seems pretty cool. I do get some low mileage figures when driving, like 23 when I normally see 32-35. I suspect that is the DPF doing its thing. But it goes back to normal after a few miles. I am VERY pleased with the truck. It is actually quieter than my wife's MB GLK 250. We opted for the truck on a recent road trip over the MB. Forgive the rambling nature of the paragraph.I just bought my 2016 duramax and have about 250 miles on the engine now. My questions are 1. When starting do I need to give the coils time to warm? 2. When should I change the oil myself (with exception to the 5000 factory change) during the break in? 3. What are some good transmission temp ranges during startup/warm up I should stick to prior to driving?
I know this is an old thread, but Dexos 2 is still a bit of a mystery to most people. To shed some light, the defining characteristic of Dexos 2 compared to plain old Dexos is that it's a low SAPS oil. SAPS stands for Sulphated Ash, Phosphorous and Sulphur. These compounds are beneficial in that they are anti-oxidants, detergents and provide wear resistance. However, they are harmful to particulate filters and catalysts, and thus, a low SAPS oil is highly recommended for use with modern diesels as they have all these emissions devices.By now your Duramax has met the break in requirements specified in your owners manual...My question, have you changed your oil yourself? If so, where did you find the Dexos2 oil? Auto store, mail order, dealer???
The Dexos2 is hard to find in stores which makes Sat morning project a week long effort. From finding the online on Monday, waiting for it to arrive by Friday, and finally changing it on Sat.. I am doing a post break-in change at 2500-3000 miles just to flush out the concentrations of boron, phosphorous, silicon and any other elements that might have remained from manufacture....The dealer probably wouldn't comp an oil change this early even though I get 2 free a year for 2 years.
