Stock tires. I plan to stick with them or something similar. On other vehicles I’ve found more aggressive tires to be a huge contributor to lowering fuel mileage. Particularly on more fuel efficient vehicles. My 01 ram 2500 Cummins didn’t care what tires were mounted. I’ve never gotten stuck...

Over about 10k. I drove more than that but excluded fuel ups where abnormal driving took place, like towing. I only fueled up at “trusted” station on level ground. Usually using the same island and pump. This was all on summer fuel. I have tested economy on winter fuel with other vehicles. I’d...

I agree and disagree. In most fuel injected engines, I would agree. However, on many of these modern boosted vehicles, they were actually designed around 91 or 93 octane. If you can find the technical paperwork and fine print, you’ll see the quoted hp and mpg numbers are based on premium fuel...

Can’t go wrong with that. You’d probably be fine even on 87. The owners manual does recommend premium while towing though. Can the butt dyno tell? Probably not.

I’ve had 3 vehicles that could hit that 650 mark on a tank. Something about being able to hit that range just feels good! I always have to take a leak before 500 though, so doesn’t do me much good. On my diesel powered trucks it was nice since it may be harder to find a station.

Probably, especially on a naturally aspirated engine. If you enjoy it though, why not. I run road diesel with extra additives in a tractor that would probably run on used trans fluid! I just feel better making sure it has good clean fuel.

That would be fun. Expensive, but fun!

I did some long term testing on mpg, and figured I’d share. I drive about 25k a year. I’m in oil/gas. Calculating heat rates and efficiency is a big part of my daily life. I know some will not agree with the validity of the data and that’s okay. I followed the generally accepted test protocols...

Thanks for the right up! Very helpful. I’ve always used bug shields to help rock chips on the hoods leading edge. My commute is terrible for that. I have a weathertech on my f250 that works well. My issue is the rubbing on the paint where it wraps around for mounting. Are you still happy with...
