Yes, it's called Active Fuel Management. There are a few devices on the market to eliminate this without going the route of a complete retune. Some people just want it in V8 mode all the time.Smoke'n Mack said:Do these new Chevy's still shut cylinders down at cruising speed?
That's a very impressive average over 16,000 miles with that combination.kish75 said:My 2015 double cab Silverado 5.3l has around 16000mi on it now and has a cap that is taller than the cab. Even with running 4 heavy 10 ply tires all winter the lifetime average is around 19.5!!!! Yes they also shut down to 4 cyl on the highway...
That truck gotta to have wings or you hit one to many buttons are your keyboarddmccoy1 said:My 2012 2500 HD with the 6.0, now has 146,000 on it, I just put the 2nd set of tires on it, and changed the front brakes at 130,000. Other than that, I have done absolutely NOTHING to this truck, but drive it. Not sure what more you can ask from a vehicle. Still have my 03 1500 at home, use on occasion, just had to replace the trans at 251,000, original motor, rear, even the frickin original exhaust system is still on the thing, can't believe it. Just now had to take to get a little rust below the one back door taken care of. Yes, I'm a chevy truck die hard, but only because they have treated me extremely well!!
PS. the 6.0 gasser averages about 13.5-14.5 mpg, since new.
Consider yourself lucky. I had an 05 Titan with SRA's that had 11 flats in 22k miles. They were that bad I just kept the spare in the bed. The last 2 f150's I bought had them and I refused any deal until the dealership swapped them for something different.dmccoy1 said:Sorry if it was confusing, yes, The original tires that came with the truck were Goodyear SRA's, I replaced them at 71K, I just put another set on it at 142K, I got 71K out of each set. To be honest, they didn't "look" like they even needed it, still had decent tread, but since I drive the truck so much, I noticed it in the ride, etc. And replaced. Goodyear SRA's are not a expensive tire, which is why I was very surprised with the life i'm getting out of them. I know i'm not switching, as long as they last. Just fyi, they cost me $211 per tire, put on, or 20" tire, very reasonable.
My 91 Dodge came with GY Wranglers on it. They were shot around 12k miles. Center of tread was worn down, as if they were over-inflated but they never were. Friend that had the local garage said that was common with those tires. Haven't bought any Goodyear skids since.Not too fond of the Goodyear Wranglers that came on the current Silverado.
