Fawk that’s beautiful!!!!

I don’t know why it posted it twice. Every once in a while it will do that. Thank you for your insightful knowledge! You seem to be a real contributor here!

Ok Karen you know it all !!!

Ok there keyboard warrior!!!!

Update im at 10000 miles and am getting 25-26 mpg work and back. Engine is getting better and better

So your pulling 10000 lbs with 2.7 turbo and getting 16 mpg?

Called three service mangers at three different dealerships. All agreed that it is suppose to be gm filter and gm oil for first oil change. No one said ac delco was king! Did they use super tech oil from Walmart as well???? Oil filter way to tight, drain plug way to tight, non oem oil filter with a sub par media for filtration, now I wonder about the oil. Cheapest ****** they could find in 55 gallon drum. It’s the point that gets me. GM did the free oil change for a reason. Not just be nice to you. By the way . There are a difference in filters in the media that is in the filter for filtration. So not all filters are the same. I’m not trying to be argumentative but I’ve been in these dealerships and I know what gos on. I bet you they billed gm for an original ac delco filter and gm dexos oil. I would never put a parts master filter on my truck. If I knew they were going to do all that. I would have just changed it myself and saved everybody the trouble. There’s no harm done and your right in a way but it’s just sneaky to treat it like it was a cheap trade in vehicle on this brand new engine. When I take a vehicle to a dealership I assume I’m getting oem parts. I know people are going to disagree with me and that’s ok. Everybody has there way of doing things. I just feel this was sneaky and cheap. This is why I left the dealerships.

While I was at the dealer getting the oil changed I bought 4 oil filters and 2 air filters to keep in stock at my shop. I also bought 10 drain plug gaskets to keep in stock. The very same day this was done. They had 18 oil filters on hand. The service writer doesn’t know I had purchased these parts because after the first one I would be servicing my truck. I’ve been a tech for 30 + years. Also what I didn’t mention in the first post was how tight the drain plug was. Suppose to be 18 ft/lbs. there is no way that way 18 more like 30-35 bad for aluminum treads

I took my truck in for the first oil change that is free from Gm. Dealership changed it at 5255 miles. I’m at 10037 now and I change my own oil this time so I drain the oil then pull the oil filter. Oil filter was overly tight. I noticed it was a parts master oil filter. Where is the GM filter? I called the dealership and they said they were out of original oil filters that day. I asked him why did you change it then. Why didn’t you reschedule! He had no answer.

56 here . I didn’t gain wisdom and become smarter. The world around me got dummer ,works in my favor!

Wow! Did this answer your question??? The simply safe guy is out of work now. Jk thanks for the info.

Update: work and back is up to 26.4 mpg with a 4wd z-71 5.3 what other 1/2 ton v8 4wd can do that?

Was yours a 4wd?

Mine thought is better to have it and not need it, than need it and not have it. But I’ve rarely use 4w low. By the way there is no way I’m taking this brand new 65 k truck off road to the woods anyway. I have a 84gmc Jimmy with a 6.2l diesel for that. 86 K10 or a Honda rancher.

I agree that is one of those time when it is useful.

Hope this gos well for you, brotha

One of the lifter is leaking down when it sits. Pumps back up on start up. This is just my guess

I’m getting 26.4 mpg on the interstate to work every morning I’m 46 miles away from home . what other half ton v8 can do that? I’m not to worried about the DFM. That may be a crazy statement but I know I can delete it when I’m ready. Ive ordered everything except the cam. They are sitting on the self. Im waiting on it because by the time 100,000 mile are on the clock I may have the money for a supercharger, in which case that would be different cam specs. I hope this helps someone. God bless

Yes DFM kits are growing and that’s good, at least it is from me. I have no problem going into this engine an doing the DFM delete. Most people do not that ability. I think the point you mentioned is spot on. All 1/2 ton trucks have issues. So I pick the one I know the most about. I have a 100,000 mile warranty on this drivetrain. Once that is out I will remove the DFM. Most companies will have the program to calibrate this ecm after the swap. Which I can do. So it’s the best of all the evils that are available in 1/2 ton trucks

Great question I would love to get rid of them.

I totally understand. I’m 56 and have been a tech most of my life. I want one new vehicle before I retire, I’ve never owned a new vehicle in my life. So I pulled the trigger on one. My 2004 Silverado which I still have is and excellent truck. 5.3L 347,000 and still going. Just mantaince on her. After warranty is out on May 2023 RST, I’m pulling it into the shop and doing dfm delete I’ve already ordered everything from Gwatney performance In Jacksonville. Then I’m going to through her on the trailer and take to them for the reflash on the pcm.

Ironically, I purchased a 2023 RST z71. I was looking at the custom 4x4. Then we got hit with a huge hail storm in the middle of June, it destroyed my truck and my commuter work car. 2004 Silverado and 2011 Chevy Cruze ( loved this little car) had 324,000 on her. 04 Silverado had 347,000 well got a great payout on them and with buying them back so that gave me a big chunk to put down on it. When I went to purchase the truck Custom 4x4 which will be the first new vehicle I’ve ever owned) the dealership had this RST and convinced me to drive it. When I drove it I was hooked. It had a 5.3 instead of the 2.7L .two stage transfer case, instead off single stage. The dealership which I know really well made me an offer I couldn’t refuse. I love the updated interior so I went with it. I’m now considing a way to get the custom also. My step son needs a truck and I’m pushing him in that direction 2024 custom 4x4 2.7l. I can’t help it. I really loved that truck I drove for a week. Don’t get me wrong, I love the RST I just want both. They are a lot alike but totally different if that makes any since. I’m a tech, I train the other techs through out the state. I’m responsible for working with the software companies that the states uses to repair vehicles, gas diesel on off road. Gm has knocked it out of the ballpark with these trucks. The structural build of this 2.7 is incredible almost like Cummins block in the way the block is built to handle the pressure and temperature changes from dual volute turbo. There is a clear defined reason for everyone of these trim levels out there. That custom with the single trac transfer case is very capable of doing everything most people need in a truck. Hope this help

I have a 2023 RST with 5.3 it performs flawlessly. The fuel mileage just gets better and better. I got a 100 k warranty thrown in with it when I bought it. If ever the lifters go out I’m going to go in and delete the whole dfm. I’m a tech so that save me some money. I have a shop and every thing I need short of a tune and that’s where Gwatney performance come in. I’ll tow it there and have it tuned. I got 26.4 mpg going to Hot springs here back in December when we went to see the Christmas lights there. My average lifetime in the truck is 22.1 over the 8300 + mile on the odometer. On my drive to work which is all interstate I get about the same mileage and it 46 miles there and 46 miles back. I don’t get the same on the way back because of the traffic. But in the morning. It does great.
