The additives are indeed the issue. Chevron's Techron is respected to the point that Mercedes Benz re-labels it as their own brand of fuel additive and sells it as such. My old Jeep gets better
milage with Chevron that Arco's econo swill.

I'll bet MB charges a lot more for their labeled additive Thats funny about the chevron, because I have had a couple people tell me here locally, that they get better mileage with Arco.

I wish that was the case with me---Arco is 10 cents cheaper here than Chevron. By the way, if you want a fuel additive that actually works try BG's 44K. I've worked in dealerships for 35
years and its the only one mechanics will say good things about; smoothed the rough idle in my old Cherokee in about half a tank. And no, I have no stake in the product or the company.

As I think back to when I bought my 2004 Tacoma, the sales man told me to use the cheapest gas I could find. That's what I have done for over 50K.
The same with my wife's 2002 Camry for almost 100K. We have had ZERO problems with either vehicle.

When I was a teenager, I used the cheap gas. My car ran OK, but there was always some kind of stuff leaking around the carburetor. (Carburetor? What's that?)

The wife had a Nissan Maxima(1991) that had about 60,000 miles on it when we got it. She would always buy gas at the cheapest place she could find, and when we finally sold that car, it had 247,000 miles on it. The only thing changed was the water pump, timing belt, and a starter. It still ran great when we sold it

Alegedly MB also relabels Militec as their transmission additive and marks it up 10x.

I agree additives are the key. The only way you will know is by checking your mileage. I can pick up 1-3mpg with Chevron, Shell or Sunoco over Sheets or Exxon. As for high test, I have one car that requires 91 octane minimum and the others do not. When it's really cold or I have an overheating issue I tend to pony up for the high test to make sure I start and can get home as it burns cooler.

About 40 years ago I did my own tests and found that Shell left less deposits on the plugs . I then met a technician who had tested fuels and confirmed my tests.
Additives certainly can make a difference .In lubricating oils it depends on how much it's refined and what the additive package is. A highly refined oil like turbine oil has no paraffins but a poorly refined one will. Paraffins will precipitate in cold conditions.
