AtlastGS Posted April 22, 2005 Share Posted April 22, 2005 Curious if you spend the extra 2-3$$$ to use premium? Quote Link to comment Share on other sites More sharing options...
TurboGS300 Posted April 22, 2005 Share Posted April 22, 2005 Yep, search it's been covered. <_< Quote Link to comment Share on other sites More sharing options...
deadmilenko Posted April 22, 2005 Share Posted April 22, 2005 Premium only! It only costs around $2 more every fill up and it better on the motor and you get a better MPG ratio. Do the math its a no brainer. Quote Link to comment Share on other sites More sharing options...
Lexusfreak Posted April 22, 2005 Share Posted April 22, 2005 Sunoco Ultra 94 is all I use! :D B) Quote Link to comment Share on other sites More sharing options...
apatrules Posted April 22, 2005 Share Posted April 22, 2005 Sunoco Ultra 94 is all I use! :D B) ← That's what I used to do, but unfortunately Sunoco 94 is disappearing in the East. Most places only selling Ultra 93. Quote Link to comment Share on other sites More sharing options...

Most places only selling Ultra 93. ← No 93 in Canada.......only 87, 89.5, 92 & Ultra 94. Since we have only 4 major gas companies that's by far the best. When I travel to the states, some friends on this site & CL suggested I give Chevron 93 with Techron a try. I was VERY impressed with it's performance & fuel economy (over 500 miles twice on two seperate tanks of gas......although it was mixed in there with the Sunoco)! :D B) ;) Quote Link to comment Share on other sites More sharing options...
LexKid630 Posted April 22, 2005 Share Posted April 22, 2005 If the manual says to use premium, use it.....when my wife had her 03 gs430 she put mid-grade by accident and there was even a difference... Quote Link to comment Share on other sites More sharing options...
deadmilenko Posted April 23, 2005 Share Posted April 23, 2005 Conoco Premium 93 because I own a Conoco "C" Store, and no I dont get a discount on my fuel. Quote Link to comment Share on other sites More sharing options...
