Snow White

0W 40 from lake speeds info, I interpreted as a waste because it barely exceeds the 5w-30 from napa. and amsoil is liquid gold..... not arguing they aren't factually "better" but the roi seems low. thanks for sharing the data

I'm paying less than half for the NAPA, am I right?

not that hard to prevent, kill switch on the positive battery cable, no dumb thief is going to be smart enough to look for a kill switch and just hide the switch in the frame rail.

if it has no computer, no abs, a manual transmission, and no emissions it'll cost you 1/2 of a new truck but is still 40K... and is probably in very good shape. the safety is far less.... thats the down side. K20 is the way if you ask me. rebuilt 454 is great. ideally you have holley efi on it and you'll never buy another if it doesn't rust out. square body forever.

my 5w30 is tracking less wear metals than your green at 15,000, think? napa dexos 5w-30 https://www.facebook.com/photo?fbid=10240827150721879&set=gm.25380156778344267&idorvanity=2098942210225719

mine has sat for over a week no problem

interesting. i have a 2024 with exhaust suitcase muffler delete and use remote start almost all the time and remote start has no impact on mine, i'd know for sure with that terrible subbie sound which my 2009 had with AFM

is there a dark mode for the forum, this white is brutal on my eyes thanks

it's great when it works and terrible when it doesn't. rivan, audi, gm, all use the same stuff more or less and it's auto level air not what you think. it's slow as ****** and annoying when towing with a WDH.... it's a real pain to setup a WDH because you can only have like 3/4" change in rake else the trailer is hung on the auto level air, the WDH is unloading and it's a mess. i had it on my ram but figured out how to maintain the rake and stay within the front/rear (rake) tolerances. so long as the front and back drop together, you're good. the systems are nitrogen filled and over time they leak, and replenish themselves with outside air which is highly prone to freezing and breaking lines whatever. the pumps also over heat if you actually use the damn thing. i had 125,000 miles on my ram with the auto level air and specifically got a 2024 yukon with the max tow package magna ride BUT NO AIR!!!! the 2025 max tow package forced the E-Diff on the yukon which would've been nice but it also forces the auto air level because of the packages they use. i'd freaking avoid that self level air or understand what you're getting. arnott is ok, hit or miss, but my plan had i not spun the no.2 main on the ecodiesel, was to delete the air from airdelete.com. it's cheaper to put in a eibach level kit than to replace 2 air struts, no joke. my best friend had maganride in his 2016 denali sierra and opted for a 2024 SLT less the magna ride. he tows a 35' jayco twicea month.

posted a reply to your other post but that's likely a spun rod or main bearing, if you're luck a wrist pin on a piston but that's definitely rotating mass. for what it's worth, i had an old v6 s10 with a poorly reassembled rotating mass that knocked the same way for over 50,000 miles lol. the bearing clearance was too much i believe on a main.

a 5.3 with a rod or main spun? that's kinda rare compared to the 6.2 but thats not good. send in a oil sample.

I've posted all my oil samples on the facebook group associated with this forum. just search for my name but it took 15,000 miles to get past break-in and i'm seeing identical results on the GMC terrain we have, 15,000 miles for break-in. search for john hammer on the fb group. https://www.facebook.com/groups/NextGenTahoe

the methodology rotating disc method RDE at speed diagnostix is superior to ICP method. you get what you pay for.

one-piece bearing and crank modification, up next, block inspection port mod.

just drained my Napa 5w-30 and put on a new WIX. Waiting for the lab kit, forgot to order it before i did the drain but the drain is more important than letting the oil sit in a cleaned out vitamin water bottle with a cap for 2 days LOL. (i used soap and water and rinsed it excessively). i'll post the results as usual. this will be a 5K OCI.

emailed lake he said not to change viscosity without UOA. was looking at valvoline VR1 and valvoline advanced. only the 20w-50 has the correct NOOACK value. VR1 is not good for catalytic converters I read? outside of boutique oil, the napa version of valvoline seems really good. i have 2500 miles to go before my 5k change. it'll take 2-3 drains to get all the 0w-20 napa out of there. getting 19mpg with a range installed, 3.5" ready lift, 33x12.5R22 nittos... hard to argue with that. not that i care much about the mpgs but it's notable for others.

big fan of lake speed jr. 0-20 oil is a joke, it's epa oil, thinnest possible oil to get most mpgs for their fleet mpg and reduce fines. do we care about that.....? NOPE. i used napa 5w-30 because the viscosity holds better than the barely 40w supercar mobil 1 and has more molyb in it according to tests. i'm at 7500. took out the oem at 1000, put in 0w-20 napa at 1000-5000, now running 5w-30 and will probably stick with it. instantly went quiet with the 5w-30 for what it's worth. i might try a 5w-40 if i can find a dexos version of it.

I put Napa 5w-30 in mine as I'm doing several tests with speed diagnostix/lake speed jr. the 40 weight barely passes the viscosity to be 40 and the valvoline 30 holds the viscosity better and has better additives than the mobil 1, allegedly, specifically the molyb. soon as a put the 5w-30 in, it went nearly silent. 20w oil is a GM game to run the thinnest possible oil to get every .1mpg they can across 800,000 vehicles because it reduces their fines raising their fleet mileage. as an owner, i don't give a flying ____k about MPG, i want it to last. I towed 6500lb 30ft travel trailer with the yukon packed to the gills into the adirondacks and that 5w-30 we will see how it test out.

your future is my ecodiesel if you get the 0w-40 oil. 138,000 miles just roasted the rear main most likely based on noise next to the bell housing. caught it immediately with the "new diesel knock" which isn't that easy to catch being a diesel. drove it 60 extra miles to get the forbidden glitter on new oil and filter, jackpot bingo card on the glitter, she's dunzo. as a matter of history, stellantis did a recall on the ecodiesel to reprogram the transmission shift points to removing low rpm lugging on the crankshaft and main bearings. they also changed the oil weight to 0-40. i didn't do oil analysis on it but i caught it immediately. there was no extended warranty offered by stellantis and no engine replacement unless you were already under warranty. i had 120,000 mile warranty and she gave up at 138,000. 2018 quad cab ecodiesel for sale, needs a bottom end rebuild. few shops line hone them and put in oversized and wider bearings, coat the pistons, and use superior bearings from germany than the ****** ventormotori used, trash bi-metal. top end, cam, all likely fine. no rust.... and nobody will want it. proceed with caution.

i have 33x12.5 on 22x10 vossen hf6-4 but the wheel well liners are trimmed

the cold start noise is gone. could be placebo but it runs better, idles better, probably placebo.

I just put napa 5w-30 in my september built 2024. the 40 weight mobil 1 oils according to lake speed jr barely meet the 40 requirement, might as well use 30 which is an excellent oil with valvoline base. this is my second change, 1st was 1000 miles this one is at 3,900. i see no obvious forbidden glitter. oil is going to speed diagnostix for testing.

denying a warranty for using 40 oil, I would expect the opinion of a tribologist to be a lost position by the manufacturer with oil analysis to accompany it. In my opinion, which is not worth much, it wouldn't even make it to arbitration and I'm going to 40 oil with my 100,000 mile warranty and I'll fight them if it blows and they try to deny. 10% of ecodiesels failed for similar reasons, crank manufacturing issues and main bearing issues, they recalled all of them and changed the oil spec..... thats it. nobody got a new engine unless it blew AND it was under a warranty. if it blew outside of warranty there was no recall for a date range to get a new free engine.... GM>STOLEANTICS

well I slid under snow white today, what a pain in the ass to that engine tag but i got it.... September 14, 2024.... a saturday engine!? not sure if that's better or worse than a friday or a monday but it's O.T.!!! when my dad and friends worked at harrison/delphi there were a lot of jokes about friday and monday builds. My best friend has a Sierra SLT with Max Tow... April, he has the recall on his app. he tows a 7,500lb 35ft travel trailer but hasn't towed with it yet.... freaking sucks. interestingly he got his in november and it had been damaged in transit but the dealer didn't disclose it, he subsequently hit a deer on the same side of that other damage, and the shop he got it done at showed him all the shitty work that had been done prior... went back to the dealer and they gave him a 100,000 mile warranty for the bs. that's one way to get the warranty i guess. feel bad for people in the recall range but on the bright side you've got a new engine waiting in the wings i guess.

i like that guy hes funny
