Going to switch to conventional oil and a wix's filter and see what that does. I change my oil every 3000 miles and the mobil 1 is black when it comes out.

So it could be either. This is what I might try, put some seafoam in the oil to help clean any sludge or build up. Run it for about 100 miles. Try some chevron supreme oil and a different filter than ac delco one, maybe mobil 1 or wix.
03blackz71 posted a topic in 1999-2006 & 2007-2013 Chevrolet Silverado & GMC Sierra 1500Well I have the dreaded 6.2L lifter tick at cold start up. It has kind of did it since 10k miles but now at 45k miles it is more noticeable. Lasts for 2 minutes or so. Sounds like it is a diesel when I leave for work in the morning. I run mobil 1 with acdelco filter since i bought it with 9k miles on it. Other than start up it runs great and doesn't burn any oil.My question is, is there a different oil or additive that I could use to help quiet it down?
I have a set of used 07-13 Silverado LED black and red taillights. They function like they should . They are in ok condition but one had a corner broken off. I glued it on and put black vinyl over the corner. From a distance you can't notice it.Asking $100 shipped for them

03blackz71 posted a topic in 1999-2006 & 2007-2013 Chevrolet Silverado & GMC Sierra 1500Will an exhaust from a 2014 silverado 6.2l fit a 2013 silverado 6.2l without modifications? Reason I ask is I can get a lightly used magnaflow system
03blackz71 replied to TT32VGT's topic in Wheels, Tires, & TPMSMy toyo at2's do it a little bit at slow speeds but not bad enough to get different tires. Plus different psi does affect it also.
Just got back from a 600 round trip from last weekend at the in-laws, yesterday. Took off stock wheels and put my 305's back on. Worth the swap, trip up there I got 16 mpg. On the way back I go 18 mpg!! I was surprised!! I found that 72-73 mph was my sweet spot on the freeway. I guess I can get decent mpg out of the 6.2L.
Just finished changing the oil in the truck. Gave it some fresh Mobil 1 at 41000 miles. Also took the 295/55/20 Toyo at2 off and put the stock 17" rims on. Going on trip next weekend and stockers ride soo much nicer, are quieter, and get better mpg. Plus when I get back, the truck is going in to get the transfercase checked out.
