I've seen engines that have blown fire the oil off to everywhere else in the engine. Cooling system and filling up the exhaust.

Plus just blowing it out the side of the block.

So for them giving me that excuse it wouldn't fly.

I'll tell you what...I have yet to see one of these trucks come in not low on oil...the longer the interval, the lower the level. Just saw one today...10,000 mile interval...hardly a drop on the stick.

I had a guy on here tell me that he does 15,000 mile oil changes and only uses half a quart. Yeah rigggggght. Oh ok. Winner winner chicken dinner! We have found our winner!

Are you talking about these wonderful new cylinder deactivation engines? It not unusual for engines not to use oil prior to those. I’ve had countless new vehicles. I would be surprised to see them use oil. I have 5 now only one uses oil. It’s stroked and blown, the rest not a drop. Ones 18 years old, 15, 8, and 2.

I hope this is documented.

Then the policy should be after x times (2?) your truck comes in with low oil your motor warranty is gone.

You can't fix stupid they say but you can try to remedy the problem.

Yes, definitely the direct injected AFM engines.

I too have some old fashioned port injected, non cylinder deactivation engines in the family and non of them really use oil. I mean, I might use half a quart in 6,000 miles, but that's about it...meanwhile my own, well cared for 2018 5.3 Silverado uses around 3/4's of a quart in 5,000 miles (more in the winter). And this is mostly easy easy highway miles...80 miles a day. Truck has 38,000 babied, well cared for miles on it.

But I love the truck...runs great and I am starting to see some high mileage newer Silverados and they have been relatively trouble free.

hey if you think about, it , the oem pcv system sucks oil like crazy , probably a quart a month, but then that could be normal. just need to maintain your truck.

I have gone 7k miles on an oil change with AFM disabled and didn’t burn a drop of oil on my 18 Tahoe 5.3. Now has 15k on odometer. Now the transmission that another story

I'm not so sure I buy the claim that 4 quarts of oil caused the engine to grenade. However, I am not familiar with the Gen V.

I would go back there and look at the disassembled engine and look the parts over. A lifter that turned in its tray could have started this, a rocker coming apart, etc. Especially inspect the oil pump for wear.

it's true my VVT cam shaft is damaged on my Gen IV

the oil pan was bone dry

oil is cooked blacken (it just means it ran low and overheated )

ran low on oil because the bone heads at pepboys damage my engine, by NOT tightening the oil filter correctly so all the oil leaked out on a 160 miles trip

My VVT system sounds like a unfortionly like a diesel engine now... :mad: MAD right now upon start up

my unicorn is died RIP born Jan 2008- died 9/29/2019 they killed it

At what point is the light supposed to come on?

On my 2014, unbeknownst to me, the oil pan gasket started leaking. When the 'oil level low' indicator showed up on the DIC, it took ~3 quarts to bring it back to full.

I say agian, oil dipstick is there for a reason.

Why not use it?

Sounds like we should plumb our pcv systems back into the oil pan rather than the intake lol.

thats what BMW did, and if the drain side hose loosens up or leaks to atmosphere the pcv will suck the oil out the crank case... GM has a good design, just maintain the system.
