The only on-road diesel sold for the last few years is ultra low sulfur. Diesel #2 is sold until winter gets too cold for it and then what you get is a blend of #2 and #1 or, if it's too cold it's #1 only (#1 diesel gives less power and lower mileage as do the aforementioned blends). To bring more confusion there is biodiesel which in lower percentage blends (5 or 10% during summer) runs about the same as #2 but a little cheaper. On a trip through Oregon I found that 5% to 20% biodiesel is required there but I couldn't discern and power reduction and the mileage was as good as I've ever gotten. I have no idea how they will deal with the winter blend. A benefit of biodiesel is that it lubricates and cleans the fuel system.
Thank you for your email! We have everything on shore and GM is looking to get everything stock and the line rolled out to the dealers by the beginning of June. Your correct in assuming that the part will work on both Silverado and Sierra vehicles on both HD and LD vehicles. The camera will be available at the same time, we just passed testing. Please feel free to contact me if you have any other questions, thanks! Tim Woodruff | Expeditor Sales Specialist | AAMP Global 727-803-0273 direct | 954-817-2308 text

My dealer installed the GMC headlight kit yesterday which I assume is just new bulbs and some reprogramming to allow for higher wattage. When I got home and pulled into my garage I could see that they were much whiter and brighter!
I had the same issue, at 800 miles mine was down to 57%. I'm sure it was caused by the sales guys starting the truck and letting it idle so customers wouldn't be uncomfortable. My first trip with my fiver was about 1k and the percentage only dropped 1%. Now it's at 43% /3400 miles and Onstar predicts a 6800 mile oil change. So, If you don't idle it too much and use it on long trips the oil life will likely be greater than the 7500 mile recommended oil change.
I'm very disappointed with the Sat radio reception in my new Sierra SLT. Driving into town on the north side of a mountain the built in sat radio quits for about two miles each way as opposed to the last three previous vehicles which have had the little magnetic antenna on the roof which worked on the same drive with the exception of two or three one second skips in service each way. That spiffy looking GMC antenna on my new truck's roof appears to be lamer than the far less expensive Sirius/XM antennas. Have any of you that live in and around mountains noticed that?
bcnqrgd replied to 2009GMC's topic in 2015-2019 Silverado & Sierra HDTwo questions: 1. Will the 8 speed transmission be strong enough to put into the HDs? 2. I can understand why the new 6.2 engine won't go into the '15 HDs but when will the gas offering be updated with GDI and higher compression?
