Get a diesel and lower your octane!

I upgraded to a 2016 with a 6.2L, 8-Speed, 3.42 rear with Max-Towing Package. What a difference this setup is compared to the 5.3L, 6-Speed with 3.42 rear.

Congrats! You will love it going forward. On the Octane / Towing question, I've owned a Gas Station for the past 33 years and this question comes up a lot. My experiencen is that increasing the octane on any late model computer controlled vehicle will more times than not work against you. Vehicles today are pre-programmed to deliver timing and fuel @ the octane recommended. When you increase octane, the computer will not adjust. Higher octane makes for a slower burn, not faster as most people think. When higher octane is put into a vehicle designed to run on lower octane it will experience longer cranking upon start up, harder starting when hot, and less performance overall. Don't waste your money.
The only time a higher octane will increase performance in an engine designed to run on a lower octane is when an engine has a high carbon build up on the pistons and combustion chamber resulting in essence raising the compression ratio. We use GM top engine cleaner to clean engines when this occurs. Late model GM 3.6 V-6's are common with this condition. It will cause the check engine light to come on for a random or cylinder misfire codes. Hope this helps, ENJOY your new ride! Feel the power! Bill |

I only pull my trailer 3 or 4 times a year. I can’t justify the extra money
PLUS the maintenance on a diesel. My 6.2 suits me well.... ![]() Kurt
