Have you ever changed the lifter screen/filter??Hello everyone, long time reader, first time poster here. I was just wondering if anyone out there has ever experienced what I have on their truck or car.
I own a 2014 silverado that I purchased new. It’s got a 5.3 V8 with 80k on the clock. For the last 3 years or so it’s pretty much been parked in its spot and gets taken out on the weekends or camping trips to the desert (we live in San Diego). I don’t tow anything heavy (dirt bikes). I don’t hot rod it around or abuse it. I like to take care of my stuff. And it’s been a great truck to me and my family.
So, from day 1 I’ve used regular Mobil 1 0w20 dexos approved oil as called for in the manual. I’ve changed the oil at 5k intervals regardless of what the oil life monitor says. And about 2 years ago it developed a really weird, inconsistent tick around cyl 1.
TICK—— TICKTICKTICK——TICK———————TICKTICK————-TICKTICKTICK
each tick or ticks were 1 to 3 seconds apart
Now I’ve heard bad things about hydraulic lifter failure with these motors so I thought “oh great here we go”.
At the next oil Change by some random chance I tried regular valvoline 0w20. And IMMEDIATELY. The tick was gone. And 2 years went by and it never came back.
So, about a month ago the wife and I are at Costco and I saw the M1 on sale so I picked up a couple cases. I did my normal oil change using the same ac delco pf63 oil filter I always use and to my surprise that ol tick was back! Even my wife was like “dang! what the heck is that?” I was scratching my head too! That night it was really bugging me so I decided screw it, I’m gonna eat the cost of another oil change and go to Walmart and buy the valvoline again just to see what happens. I went and got Valvoline EP 0w20, rolled under the truck again, dumped the brand new oil, replaced the brand new filter, and I kid you not the tick was instantly gone again. I even dragged the wife outside just to have a witness.
My question is how is this possible? I know different companies use a little this or a little that here n there different but, come on, how much difference could it make? For the most part all big box oils with the same certs are gonna perform pretty much the same right? So why does my truck not like M1 anymore?
I guess I’m just going to stick with Valvoline now. I just find it to be so weird. Sorry for the long story. I figure if there’s anyplace to ask about this kind of thing it’s here. Just was wondering if anyone else has heard of something like this.
