Engine Knock/Ping on Downshift to climb hill

Honestly. I have no clue. I’m currently averaging 15.7 on the computer. But I’m on 295’s have armor/winch and carry a lot of wind drag in the roof (paddle boards/ kayaks). Plus it changes form winter to summer by about 2mpg. But I will say, it doesn’t feel like mpg has gotten any worse on 2.0.

 

From what gets posted around here, that sounds about right for those mods?

Yes. I noticed a bigger hit on the winter fuels and cold temps. It seems to be mainly from short runs (14.5mi commute) and the enrichment cycle. Doing the same on a warm motor negates the loss.

 

I don't know, i've tried 89 vs 87 in my toyota trucks...no difference. I think its more mental than reality. It was the same with my 4.7 tundra that required only 87 also. Anything higher than 87 in octane your just pissing away money.

 

Yeah, my commute is 3.5 miles, so def get hurt by the colder engine temps. Plus a lot of idle time. So it hurts my mileage a bit more. I make sure to run it hard, high rpm’s from time to time. I check my oil a lot and it’s still good at 10k mile intervals.
