Molal24 Posted November 3, 2008 Share Posted November 3, 2008 You know I've realized that too. In the city when I use V-Power I get about 18 mpg, but when I use Speedway Premium I only get 15.6-15.9 mpg. Link to comment Share on other sites More sharing options...

snow05gtRI Posted November 4, 2008 Share Posted November 4, 2008 well good to know that it was useful putting shell in my car all this time. on my last fillup i put in 20oz of techron injector cleaner and then filled the tank with v-power....could anything bad happen from using injector cleaner on top of the v-power which already has injector cleaner in it? I feel like my MPG has actually gone down with the cleaner in it, though it has only been short term so i cant say for sure. Link to comment Share on other sites More sharing options...
Molal24 Posted November 4, 2008 Share Posted November 4, 2008 Speedway premium is only 92!!!!!! I could have swore it was only 91. LOL either way I stick to the V-Power now which is 93. Link to comment Share on other sites More sharing options...

Make sure you let this tank go down to the E and then fill up to full again. You'll see the mileage go up. Link to comment Share on other sites More sharing options...

LOL either way I stick to the V-Power now which is 93. who cares what grade it is why would you put that crappy gas in your car?? Especially when you can get shell v power or sunoco 94.

fishbone Posted November 6, 2008 Share Posted November 6, 2008 Shell V-Power is not inherently good gas just because it says Shell V-Power on it. I picked up bad Shell V-Power gas from at least 2 stations here in Lincoln, per my datalogs. I then switched to BP which also now has Invigorate and is a point higher in octane [91 vs 92] and everything has looked a lot better in my logs. My opinion ... V-Power or BP Invigorate, they are both good, just make sure you fill up from a gas station that gets a fair amount of traffic rather than one off the beaten path which has gas in it's holds who knows how old.
