AngelOfDeath Posted December 20, 2006 Report Share Posted December 20, 2006 Besides Seafoam..anything I should do to help out with the mileage. I thought I saw someone said that they put chevron high tech or something after they did their seafoam. Got to get ready for a long, ut well worth drive.

mts Posted December 22, 2006 Report Share Posted December 22, 2006 I have seen the brown haze that comes out of an S burning Midgrade.... I am not going there. Quote Link to comment Share on other sites More sharing options...
MazdaMomma Posted December 22, 2006 Report Share Posted December 22, 2006 my mechanic told me i could use mid grade every 4th tank, but the milli would just backfire and i could hear spark click, so she got nothing but high test all the time.

mohamedeladawy@hotmail.com Posted December 23, 2006 Report Share Posted December 23, 2006 only the valero premium for me. as all the mobil stations have been bought up by valero. i use shell sometimes as well. Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted December 23, 2006 Report Share Posted December 23, 2006 generally I buy gas at either shell or mobil.  but ONLY prem  You can put in what you want, but it will be your fault when it goes to hell.,  seaform can either do wonders or cause vacuum leaks to open up by removing carbon that has built up in the leaks, the best thing to do with high mileage is run some fuel cleaner through every 6k, and change the spark plugs more often Quote Link to comment Share on other sites More sharing options...

Like I said only once in awhile I will use midgrade. Use prem the rest of the time.  Quote Link to comment Share on other sites More sharing options...

Renboy Posted January 3, 2007 Report Share Posted January 3, 2007 Fuck that, I use regular on a 10:1 engine and it's fine. The milly's 8:1 would be fine with 75 octane let alone 95. If you're putting in premium you're just paying to have worse gas mileage. Not to mention polluting the precats with hc's. And MC, it's worse to keep switching than to just stick with the lower octane. Â If you're going on a long road trip, overinflate the tires, use regular gas and change oil before the trip. Besides that, make sure all bulbs work, and keep a spare for each one with the spare tire. Oh, and check pressure in the spare too. Quote Link to comment Share on other sites More sharing options...
mohamedeladawy@hotmail.com Posted January 3, 2007 Report Share Posted January 3, 2007 what? i know for a fact that the milly is shit when regular is used. Quote Link to comment Share on other sites More sharing options...
AngelOfDeath Posted January 5, 2007 Author Report Share Posted January 5, 2007 Well I used prem vs regular on my trip and got better mileage with prem. Quote Link to comment Share on other sites More sharing options...

latinopikachu Posted January 10, 2007 Report Share Posted January 10, 2007 i agree with anbuis and angel. Â it's not really a big difference between fillup with reg and premium, like $1 Â the millenia does indeed run like CRAP when you put in regular. it's sluggish and a total beyatch; not to mention gets HORRIBLE gas mileage.

Troutman Posted January 10, 2007 Report Share Posted January 10, 2007 I can't speak for other markets, but here, the premium fuels have additives which negate the need for injector cleaner additives etc. Piece of mind for any car I think, especially a car which requires premium to start with.

Â In the states we have Chevron and Shell which both have cleaning agents inside them. I use the premium fuel as well. I notice a difference with my 95L between regular and premium. Not a HUGE difference, however. My 96S is still under construction, but that will only smell premium when it's complete. Quote Link to comment Share on other sites More sharing options...

mts Posted January 17, 2007 Report Share Posted January 17, 2007 The octane levels are not the only concern when using premium gas... as some seem to think. But there are other additives also. Like detergents and actually cleaner fuel quality. Quote Link to comment Share on other sites More sharing options...
Troutman Posted January 18, 2007 Report Share Posted January 18, 2007 Agreed, these additives can negate the need for injector cleaning down the track, among other things. Quote Link to comment Share on other sites More sharing options...

///BHRpowered Posted January 27, 2007 Report Share Posted January 27, 2007 and if your a crazy cheap ass who actually thinks there is a noticable difference in price between reg and prem then you will take the car to some shitty chink "mechanic" when it goes have problems, they will make up some chink crap, chrge you, and you'll still go cheap Quote Link to comment Share on other sites More sharing options...
