I switched from chevron gas to shell about a month back and have noticed a big jump in mileage. I'm consistently up 2mpg's or more.

Vehicle info: 1998 GS400 (stock) with 134,000 miles.

Driving info: I commute 34 miles roundtrip daily. Half is city driving, half is highway (which I go about 80mph on average).

I would dare anyone to find a 13 year vehicle with a V8 that gets mileage comparable to a GS400!

 

I don't see a whole lot of Shell Station in Salt Lake at all...

 

I guess depends where you live. I've trial and error gas stations but im a die hard Fan of Chevron. And their exclusive synthetic fuel additive works wonder for me

 

There's one right on the corner of 700 E and 400 S now!

 

problem with shell is their gas is like $0.30-$0.40 higher than everyone..........even with the kroger discount they offer

 

Chevron does not exist in NY, and Shell is rare, the only one near my area closed down so now its only Sunoco or Getty gas (lukeoil)

 

I tend to use Shell more than any other brand/company. In my area, they're usually the cheapest and have V-POWA! Haha, Chevron is next if I can't find any Shell stations on the road.

 

been using shell for years see sig

 

I always try to put shell ive been using it non-stop for over a year now

 

I only use Shell or Exxon.

 

Exxon is actually mobil. Exxon died in my area.

 

I use Costco gas, $0.20± cheaper than Chevron or Shell. But they use / get supplied gas by Chevron.

 

I use Shell (Premium 91) because they give airmiles in Canada. Nitrogen enriched fuels aren't good for the engine as you're A) getting less fuel, B) the nitrogen is actually a deterent of combustion as it isn't part of the chemical reaction within your engine. Nitrogen is also used as a key component of fire suppressant systems on oil rigs. The nitrogen is supposed act as a detergent, but I would be skeptical of its actual effectiveness. But I like to travel so I'll keep using it because I want the points. For the other Canadians, Husky has the 94 octane which is actually a superior fuel, which I use for road trips or highway mileage.

As for mileage claims, driving behaviours changed at all? In theory, your mileage should degrade using the nitrogen enriched fuels.

 

Since I had my first Lex, Ive been using Shell's VPower.

 

been using shell for couple of years now also. its the only gas i use, except when i travel out of state.
