elcamino replied to CTburban's topic in 2015-2018 Suburban/Tahoe/Yukon/Escalade Issues, Troubleshooting, & Recalls/Service BulletinsHad you been getting a coolant odor as well??? There is a TSB about over-cycling thermostat that also cause the radiator to leak (fatigue). The fix is a new stat housing+stat+radiator. Happened on my 2015 Sierra. You could see coolant staining on the radiator cores. Took several complaints to dealer to get fixed, although I never notice mpg issues but then again I never pay a lot of attention to mpg.
elcamino replied to burkie733's topic in 2014 / 2015 / 2016 / 2017 / 2018 Silverado & Sierra Issues, Troubleshooting, & Recalls/Service BulletinsBad fuel??? Or sabotage?? Have any enemies??
91 is all I can get around here, closest station with 93 is 100 miles distant. I am using 91 Murphy in my '17 6.2L Denali Ultimate, and it has no ethanol (also in my 2016 and 2012 6.2L). Most all premium sold around here does not contain ethanol. If you have a boat, snowmobile or other small engine its not recommended, primarily because ethanol blended fuel does not store well. Use up within 30 days or fuel system problems can result. Depends a lot on the age of the equipment and the design. Lots of marine problems with gummed up fuel systems on infrequently used boats as well at ATV/Snowmobiles that sit for (6) months during off season.

Coatings may slow it down but often all it does is cover it up. Rust is very common, as iron reacts easily with oxygen.
All 1/2 tons (1500) come with 6-bolt wheels, no exceptions. From what I can see, both the standard and F44 come with the same rear axle. F44 is a suspension option. Try this, GM production spec's 1990 Chevrolet Truck
elcamino replied to Wolverine350R's topic in 2017 / 2018 Chevrolet Traverse, GMC Acadia, Buick Enclave & Cadillac XT5Yah, could not pass up on it. My 2015 miles were getting up there and they offered me a good trade-in.
elcamino replied to Wolverine350R's topic in 2017 / 2018 Chevrolet Traverse, GMC Acadia, Buick Enclave & Cadillac XT5I purchased a new GMC in December and the only document I have that remotely referred to warranty is an acknowledge form I signed which explains the warranty and the service benefit of 2 visits in 24,000 miles or 2 yrs. Maybe that is what you recall?

There are roads near me that are misnamed and have not been corrected in years.
