Thanks Tachyon....all questions answered and very thoroughly!!!

20% OLM sounds like a reasonable spot for a warranty plan

Thanks for the info. What was the reason you went from a relatively new '21 to a '24? The '21 is a very nice truck.

Sounds like we have similar uses....towing a TT in 100F+ temps, towing my fishing boat weekly, plus all other common truck uses! When I purchased....I drove the truck home 150 miles from dealer in 119F!!

Did you perform any oil changes prior to recommended first at 7500 miles?

I'm new at this oil selection/analysis, as I have not purchased a new truck in many years where I can service and record from new. I want to take great care of my investment, as best I can: 2023 GMC Sierra 3500HD; 6.6L GAS/6 Speed Trans; 4x4; Crew Cab; Short Bed After doing some reading on the...

Thanks! I was a Ford guy and this is my first modern GMC. So far, I like it! Probably my last truck, so I want to maintain it as such (severe duty maintenance).

Perhaps I should also consider EP....it's just that Truck/SUV claims it is for higher temps when towing

what's that?

Hello all- My NEW 2023 GMC Sierra 3500 HD, 6.6L GAS / 6 Speed Trans, Crew Cab, 4X4... Owner's manual calls for 5W-30 DEXOS 1 - Gen 3. Manual doesn't suggest anything different for towing. I contacted M1 and they sent me the attached (see link below). When I asked what the differences were...

That only lasts so long...it's like term life insurance......plus, I'm not a fan of extended warranties

interesting...I purchased a new 2018 RAV4 Adventure model when the 2019 models were available. I wanted the 6 speed... tried and proven trans. It has the 2.5L four-cylinder DOHC 16-valve engine with Dual VVT-i, delivering 176 hp and 172 lb-ft of torque. I avoided the CVT trans that appeared in...

10 speed trans became standard on 6.6L Gas in 2024. I specifically wanted the 6 speed.....more simple, proven durability, and less expensive to repair when the time comes...because it will come

The same thing happened to me about 8 months ago on my previous truck. '03 F-350 V10....Motorcraft FL820S oil filter...leaked at seam....my first time ever seeing this! I, too, change my own oil for 44 years and have never seen this!

Boat is new...2023.....200 miles towing since new

Only one service is what they come with

5W-30 Dexos 1-GEN 3

Does that adding a dipstick include 2023 models with 6L90 6 speed trans? Haver you performed this install? What can you share about install? Parts, how is access hold opened up, verified accuracy etc? Thanks

Hello all-- RE: My new 2023 GMC 3500HD 6.6L Gas and 6 Speed Auto... Manual states, "perform the first oil change before heavy towing." In addition, "Do not drive over 50mph and do not make starts at full throttle during the first 500 miles of trailer towing." I am going to reach 500 miles in...
