Does it matter if i put plus gas instead of premiem in my 98 luxus?

Question

also is ther a difference between gas stations like cheap no named gas station and cheveron shell, etc gas stations . or is the quality all the same

Answer 1

well premium is just an octane rating for gas. and no you wouldnt need to put premium in a 98 lexus. you can put in regular. Some people think cheaper gas stations arent good for your car but most dont. It shouldnt make a difference.

Answer 2

The difference between the grade of gas is determined by the octane number. The higher the octane number, the better performance your car is suppose to perform .The octane numbers separating medium grade and premium is about two numbers. I don't even bother with this.For your info, ALL gasoline sold in the U.S.comes from only a few refineries near your location, and they all got to meet U.S.standards, so basically they are all the same, regardless of the gas station where you purchase it.

Answer 3

You're probably fine with 89 octane ("plus") gas in the car. In general, you find a lot of the same stuff at most gas stations, but Citgo is notorious for having very poorly filtered fuel.

You can check your car manual for what it recommends for fuel grade. If the manual suggests 87 (regular), then you're sorta wasting money on higher grade fuels.

Answer 4

It definitely matters what station you use. The vast majority of car companies that "recommend" anything other than Chevron do so because they have a business arrangement worked out with the fuel company in question. Case-in-point, Ferrari recommends Shell only because they supply their Formula One racing team with free fuel as a result. It's profitable for both to lie to the customer: the gas company gets business and the car company gets to overcharge for repairs caused by unnecessary mechanical stress. Whatever gas you use, avoid Arco (and all BP products) as if your life depended on it. I've seen far too many fuel pump failures as a result of pennywise but dollar-foolish idiots using cheap crap like Arco. Yes, that is exactly what happens when you use crappy gasoline; your fuel pump blows out and costs $700 to repair. Not to mention the valve damage in the engine. What little money you may have saved by using cheap junk (and then some) flies out the window, along with the inconvenience of having your car in the shop at least overnight.

I would never use anything other than Chevron for daily city driving. If you regularly drive long, empty stretches of highway, the engine probably burns well enough to strip most deposits from the pump and valves, but otherwise, I'd just suck it up and pay the extra $0.20 per gallon for the Techron. It'll pay for itself in the mid-to-long-term by preventing costly fuel pump and valve damage.

As far as the grade goes, use whatever the car company recommends: I've tried using supreme in my Ford Explorer, and the damn thing knocks like a tax collector until I refill it with regular. Ford designs their (low-end--not the SVT V8's) engines to be used with 87 octane. I know BMW and Mercedes design their engines to be used with 91 octane or higher (there are actually some models not sold in the US due to the higher octane content of European gasoline), so I would imagine Lexus (or at least the parent company, Toyota) probably recommends either 89 or 91 as well.

Answer 5

Almost all cars today are made to take "regular" gasoline. Check your owner's manual or call the dealer to see what kind of gasoline your car was made to use. You should not use lower octane than they recommend. Using higher octane is a waste of money.

The danger of using gasoline with a too-low octane is that your engine will "knock." Knocking can quickly damage your engine, and the repair is expensive, maybe replacing your engine! If your engine knocks, you should go to a higher octane, even if that is higher than your car would normally use. You should also take it in for an exam. Tell the mechanic that it knocks unless you use a higher grade of gas than you're supposed to need.

Answer 6

My brother did a study on different gasolines, here are his findings:

For LONG DISTANCES - premium gasoline will give you more miles per gallon than regular, but the price per gallon is about equal.

For local travel use regular.

As for quality and all that b.s. - the differences are minor. Some additives are good for the engine, but decrease performance.

Consumer Reports might have something on it, but I haven't looked.

BTW - I've got the GS-300, which did you get?

Answer 7

The quality of the fuel is at stake with a no name brand. As far as using plus instaed of premium. The car will tell you. If you experience hesistation or pinging when you accelerate, then plus is not for your engine. Go with the recomended fuel octane rating for your car. It should be in your manual.

Answer 8

verify the vendors instruction manual for a ninety seven Honda as to octane standards. i'd be shocked if it required greater than 87 octane. if so, you have wasted a brilliant style of money. by no potential use an enhanced octane than reported by potential of the producer. although, if the producer recommends top rate you extra useful use it. Toss the classified ads for all those gas ingredients. do no longer waste money on them

Answer 9

No plus gas will work fine. I would fill up with Super unleaded about every 5 tanks though. Hope this helps!

Answer 10

not at all...as long as the octane rating is above 89, you're ok.
