I recently became acknowledged about the myth of the 3,000 mile oil change on newer vehicles with advanced oil. I own a 2006 silverado 2500 v8 6L WT and I change my oil every 5k miles with Mobil synthetic 5w-30. I cannot seem to find the exact information within my car manual or my Haynes/Chilton manual for the recommended interval between oil changes. Is there anywhere I can look up how often I can change my oil with the specific engine of within my truck? I have heard some oils can go 10k+ miles on some vehicles. I'd love to do less oil changes, but don't want to endanger my engine since oil changes are so quick though I'd love to save money too! Where can I find this exact information or do you have any other suggestions? Thanks in advance! -
I recently acquired a 2007 Chevrolet Silverado 1500 Z71 (5.3L, 4 Speed Auto). I purchased it from my grandpa who babied the truck, and put 191,000 miles on it. It has had a shockingly small amount work done over the years and drives like brand new (he kept all of the receipts). He always goes to the same shop which uses a Mobil 1 Extended Performance filter and Valvoline 5W-30 conventional oil. Now that it has 194,000 miles, should I change the oil to a synthetic blend, or full-synthetic oil? Also is it wise to use a high-mileage oil? I changed my wife's car to synthetic oil with great effect (and I realize it is a completely different situation considering she has a lower miles car, but I just wanted to express that I was open to the change).
