Well I’ve never  listened to men,and glad I didn’t. My 2017 Silverado 1500 4.3 V6 has a 15mm (head size) drain plug. Not a 12mm as everyone seems to think. Rat bastards also upped oil capacity to 6 qts-so you gotta buy a 5qt plus another quart.You’re better off buying 2- 5 quart jugs for the money. Speaking of JUGS...if mine were any bigger I wouldn’t be able to slide under truck!

Lol!.. Not sure what to do with that info on the jugs ?.. However yes the 2014-18 4.3l takes 6 quarts, 8 quarts for the V8's.

A women who does her own servicing on her truck, I am truly impressed and if you have a significant other what a lucky person. If not, you single,...LOL.  Don't always believe us know it all backyard mechanics type guys or even some dumb ass parts guys, always check reliable sources for proper info and double check. :thumbs:

I am still tempted to get one of those quick drains. I just like the magnetic tip bolt. 

DIY oil I like a good 7quarts to start with then a week later I get back to it and at 1/2 quart additives when another week later 1/2 quart. Then pray it all stays in the engine.

Or like we've all seen in these automotive forums, pictures would help, or the more crass one, pictures, or it didn't happen. :D

No idea why anyone would say the drain plug was 12mm. GM has used 15mm since I started working on cars almost 20 years ago. The new engines all hold more oil. The V8 holds 8 when they were 6 quarts for ages.

Yeah I know. Just googled size and most posts were stating 12mm? I have an equinox which was 15mm too-and of course the book doesn’t give you specs ,just capacities. I’ve been working on cars since I was about 15-so 45 years of experience. This old broad is still wrenchin’ ! Thanks for the post !

Prove what? That it’s 15mm? I don’t have pictures of the sun coming up every day-but I’m pretty sure it happens ...

Sorry to be a bubble-buster, but don't confuse bolt head size with bolt THREAD size.

And NEVER try to force something in where it won't go comfortably.  Get some ramps, too.

My 2004 grand am v-6 has a 13 mm oil plug. There's all kinds of kinds.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
