If you read his build thread you will understand how he gets 27+ MPG. The truck is lowered, using 0w20 oil instead of 5w30 and never driving over 55mph. It is a regular cab short bed 2 wheel drive. The rest of us 4.3 owners will never see those mpg numbers.

I went from 5w30 to 0w20 in my 4.3 v6. The MPG improvement is really not much. It does go into v4 more often though. I might try 0w16 on the last oil change before I trade it in.

The 6.2 would cost $2510 more to get than the 3.0 diesel cause like you said you would have to move up to SLT to get the 6.2

Selecting the double cab standard bed with 2.7 engine as a base. With the Elevation or SLE trim. The 5.3 shows $1395 upcharge. The 3.0 shows $3890 upcharge. Selecting the double cab standard bed with 6.2 engine as a base. With the SLT trim. The 3.0 shows is the same price.

Seen the diesel is available on the GMC build and price site but not on Chevy site yet. Show it as a $3890 option and only available on double cab and crew cab models. 277 horse at 3750 rpm and 460 foot pounds of torque at 1500 rpms.

Are those all 5w30 that are listed at top? Here is some specs to compare on new oil samples. These are all 5w30 tested by the same lab.

A regular cab short bed with the 2.7 turbo 4 cylinder would be sitting in my driveway if they built it.

https://www.compustar.com/systems/chevy-remote-start-system/ Will be cheaper than going with the factory remote start.

You guys that drove these 4 cylinders. How often did it go into AFM and drop down to 2 cylinders?

I think all the OEM parts needed to do the conversion are listed in this thread with part numbers. Should be able to order those parts online cheaper than what the conversion kits cost.

Wix has a oil test kit that cost 10 bucks. Plus postage to send it in. Part number is wix 24077 on rock auto. They use a lab called ALS Tribology . The TBN test is included for the $10 plus postage. Cheaper than Blackstone

If you program with the Hypertech are you able to use the HP tuner to see what changes was made??

Grumpy bear My scan tool does not show oil pressure or oil temperature. It does show coolant temperature which on the drive home from work read between 192 and 199 degrees Fahrenheit. Dash gauge read about 210 f. Truck does have the factory towing package. Not sure if anything is different on the coolant system with tow package.

180F thermostat too cold for here in Ohio. Going by oil gauge on dash. It is right at the 35 psi mark now. Used to be just under 40 psi before. I will hook up my scan tool tomarrow and see if it shows oil pressure.

I read the same thing. The 6.2 guys seems to be in v4 mode the most from what i have read. The more torque the engine makes the more it would be in v4 mode. Dont think it has anything to do with software. I only switched to 0w20 as a experiment to see if v4 did work more often. I might do a second run with 0w20 if the uao looks good. But after that i will be back to 5w30
