I have an 07 Silverado with 4.8 v-8 and was told at an orientation at my dealership that I should schedule an oil change only after the light/onstar tells me to....I asked about 3,000 mile change and I was told that if I wanted to waste my money they would take it....but again wait for the light/onstar.......as far as full synthetic I was told that it wouldn't be necessary since motor oil technology has been greatly improved....but If I wanted to run it I should wait to at least 5,000 miles to allow the engine to settle and for everything to get seated properly.....just what I was told at my dealership....I hope it is helpful

I own a 2007 Sierra Denali with the 6.2L engine. I currently have 2,000 miles on the engine. I plan on changing my oil for the first time at 3K miles with Mobil 1 Extended Performance. I agree with the wasting your money comment about 3K mile changes, but I would be nervous going past 5K miles on conventional oil. I've personally been sold on the Mobil 1 Extended Performance (Full Synthetic)that's guaranteed for 15,000 miles or one year. I change my own oil and I find that it saves me a lot of time and hassle.

my '00 rado with 5.3 is at 260,000 miles right now and does not burn oil............have run Mobil 1 since the second oil change.
may do it on my GMT-900 with 5.3 as well.
#23 of 71 Just curious, what is this noise?

I drive a 2000 GMC Sierra 1500 with the 4.3L v6. Nothing is wrong with it but whenever I accelerate when it is cold, a fluidly sound comes from under the dash like water rushing through a big hose. It is probably normal but I was wondering what it was. Any explanation would put me at ease, thank you!

I had EXACTLY the same problem in a completely different vehicle - 2002 Nissan Altima. Turns out it was a very small leak in the radiator, and the system would not hold pressure. When the leak was fixed the noise went away. Not sure why such a small leak would cause such a big noise, but that's what it was. You might want to have the cooling system pressure tested for leaks.

I checked the cooling system and everything is normal. Could it be the heater coil? Is the heater coil located under my dash somewhere?
#26 of 71 When to change timing chain
Dec 06, 2007 (7:28 am)
I just bought a 1995 silverado 4x4 with crew cab and 5.7l engine with 140,000 miles. I cannot find anywhere in the owners manual as to when to change the timing chain. The previous owner said he had not done it. Any help? Thanks

ON most single cam in block v-8 engines the timing chain is steel
unlike some belt driven engines and is usually a "life of engine" part
and is not replaced unless it fails in most cases........................

Thanks, another Silverado friend said that he never had his changed out and he is at 200K. So, I guess I am good to go for awhile.

Driver 1 refers to the key fob you are using. Use the other one and it will be driver 2.
So assume you have power mirrors, power seats etc. You set them for your comfort by pressing and holding the 1 on you door pad till it beeps. So, next time you drive the truck, you insert key fob 1 (look for the number 1 on back of fob) and if the seats, mirror, were changed since you last drove (wife used fob 2 and set to her liking), they will remember the setting for Driver 1 and adjust to those settings.
Not possible with out the DIC or the luxury LT features. It comes with the LT option.
