Do you "have to" put high grade gas in this car?

[MotionMan]

I'm talking about a 2003 Lexus LS 430.

Some people tell me you "have to" put in high grade, or it will wreck the engine. Others say you can use mid-grade. Most agree you cannot use low-grade, but am not sure why.

Please explain your response.

Thanks.

Edit:

OK, everyone calm down for a minute. Number One: I never said I bought anything. Number Two: I know enough about cars that I know to have them serviced, check the oil, keep the tires at the right pressure, etc. I just do not know anything about what the real difference is between the different types of gas - that is why I asked. I now get that, apparently, there IS a difference and, when it comes to the LS 430, high grade is the only way to go.

Thanks for the heads up.

Use whatever grade it says to put in it.

Get out of here with your logic.

Using anything less than premium gas in an 8 cylinder engine is typically not a good idea. You might get away with it but there's a chance you will see a decrease in performance and gas mileage as well.

Do what the manufacturer says in the manual.


Explanation of my response: The manufacturer built the car, so obviously that should know what grade of fuel is best for the car.

I failed at giving useless answers. I'm so ashamed of myself. /crawls out of thread

So you buy a Lexus and then you want to cheap out on the gas?

You should've just gotten a 95 Civic if you're too much of a tightwad to spring for the gas.

I know what the manual says. I do not believe everything they say in the manual.

You're probably the type who buys an expensive car then goes 50,000 miles without changing their oil too, eh?

Just the ones that really matter in order to keep a car running in tip top shape. You know, the ones that talk about what grade of fuel to use, what kind of oil to use, etc. etc.

Yeah fvck the manual, who the hell do they think they are using millions of dollars developing a car and telling you to put the most appropriate gas in the tank. Stick it to the Japanese and buy the lowest octane gas you can find.

Ummm...they designed the car and know the profile of the pistons and compression ratios and such, I think their recommendation on what fuel to use works just fine..

I do not want to put cheap gas in it, but, at the same time, I do not want to pay for expensive gas if I do not have to.

Pardon me for trying to save a few bucks a week.

lol

You just spent tens of thousands of dollars on a brand new car, and are worried about 10-20 cents a gallon?

Just use premium if thats what it requires.

 

[Corporate Thug]

why does the poll say LS300 and the post says LS430?

High performance cars make more power by increasing the internal compression. Cheap low grade gas cannot withstand those increased pressures and it explodes. If you want gas exploding in your engine then keep putting low grade gas in your expensive lexus.

if you wanted to save a few bucks a week you wouldn't be driving a lexus

 

[waggy]

dont believe them! they are trying to get you to waste money. Put in the cheapest you can find. it won't hurt the car or gas mileage. Also don't worry about changing the oil every 3k miles. it should be fine every 10k (or 8 months) fricken oil company's trying to rip us off.

If you want to save a few bucks a week, sell the lexus and go buy a camry. Then you can use 87 octane and not worry about compromised performance.
