When I first picked up my '99 EX V-6, the salesman told me that the car should run "fine" on regular unleaded, but IF I were to put in Premium, the horsepower would "jump to" 205 or so from the stock 200.....first of all, is this just bullshit, and SHOULD Premium fuel be used in the sixth generation V-6 Accords, or should I continue using regular, which I have been pretty much doing? IS there an increase in performance by going with premium fuel, or should premium NOT be used in these cars?

What scares me is a story I remember from an old friend of mine who told me that when he used to continuously put premium fuel in his Saturn, eventually black smoke began bellowing out of his tailpipe, and the dealer told him he burned out his fuel injectors because the gas was too rich for the car.....

 

I have a 98 coupe (i4) and have used nothing but chevron supreme with techron from day 1 (since I have owned it anyway) and never noticed any problems---nor have I noticed any performance increase...

It is hard to say without having ever used regular to compare. I would seriously doubt a 5hp gain from fuel alone--unless maybe you're comparing regular to 76 cool blue or something--but I don't know for sure.

BTW pm me if you are interested in getting rid of your underbody kit

 

yea, on older cars...the lowest is preferred and occasionally premium.

maybe for vtec premium is preferred, not sure.

also, i thought that "putting in premium will lean the timing" thing was for '03 and up?

 

Hey Playa,

Thanks for hittin me back up.....sorry, I dont have any plans right now on getting rid of the underbody kit....sorry about that.....if I do anything, I was thinking of soon selling the car to get a four-door sedan of some kind, either the new Accord or the Mazda 6 with the sports package....

With regard to the fuel, thats interesting that you put premium fuel even on the FOUR BANGER....I would think to use regular there for sure; but perhaps you are right ---- this dealer probably didnt know his asshole from a hole in the wall when he said the power should go up five horses; either way, that wouldnt make a difference to me because the car is kept and maintained for show, basically, and for local cruising.....its not set up to race or anything.

I was just curious if premium gas was recommended for the V-6 engine, and/or if any damage could occur by continuing to use the premium fuel.....

 

Hey Wed,

Thanks for the reply.....so, when you say "older," do you mean in MY year car (a 99)? Would that be considered "older" and therefore better off with the regular and treating it SOMETIMES to premium?

And I dont know about the VTEC thing needing premium......the manual, from what I remember, just says the car CAN run on 87 regular unleaded....

So I was trying to get a final say on this.....

 

why is it better to use regular with older cars like mine a 91''

 

premium gas is harder to detonate (i believe, correct me if I'm wrong). I drive a 94 EX (meaning vtec) Accord, and have been using the cheap stuff since day 1 (November 2000).

 

Just use the lowest the manual tells you to. You'll never notice any difference. if it pings then get a higher octane fuel. no reason to WASTE money.

 

If it doesn't say "Premium Unleaded Fuel Only" on the gauge cluster, don't waste your money putting higher grade gasoline in. Your engine will not take advantage of the higher octane, nor will it run any better or give you any more power than regular unleaded.

If in doubt, check the owners manual. Whatever it says to use, use it.

 

nah, 6th gens are considered more of new. my friend in his '02 says he can feel a difference between premium and 87...

im talking like 5thgens and older.

as for the VTEC thing, im not really sure but most of the guys with h22 swaps in their 4th gens say they use premium for a reason.
