is BP ultimate petrol really better for the engine than ordinary unleaded, please?

Question

can you explain why?

I have MX5

Answer 1

BP Ultimate is British Petroleum's Premium unleaded, with an octane rating of 92. The octane rating is the ONLY difference between it and the lower grades of fuel.
All other additives, conditioners, and cleaning agents are exactly the same.
There is NO advantage of using premium fuel in your car unless the manufacturer recommends it. it has no more energy stored in it, and will hot help mileage, performance or your engine's characteristics any at all. It just will cost more.

Good Luck

Answer 2

UNLESS YOUR CAR'S OWNERS MANUAL AND/OR WINDOW STICKER SAYS DIFFERENT, USE ONLY 87 OCTANE (REGULAR) UNLEADED PETROL!

That said, I'll make a confession. I myself am tempted to put "the good stuff" in my tank every now and again, especially if the car's been "acting up." Even I, who know better, fall into the trap of the marketing geniuses who have spent years convincing us that bigger/higher is better.

I usually try it when what I really need is a tune up or a fuel filter change... hoping beyond irrational hope that the car will positively react to the sudden "pampering" I am giving it

To date, this ploy has never worked!

The fact is that today's cars are designed to operate at peak efficiency with the "cheap" gas. Especially smaller engines, the 4 and 6 cylinder jobs. Some super-charged 8 cylinder petrol-guzzlers demand the high-end stuff, further punishing your wallet for having the audacity to own such a vehicle... but again, I stress that your owners manual will tell you if you should be using anything other than 87!

The terrible truth is that in a lot of the smaller vehicles, the use of a higher octane petrol can cause trouble since the additives overload the engine and cause the parts to work harder.

Granted, this is not a technical review, just stating the facts as I understands them!

So in conclusion of the review, when you're tempted to give in to your car's lust for the "good stuff"... just say no!

Answer 3

I am a petroleum engineer. The main differences besides how the gas is refined is in the additive. Use the manufacturers recommendation on the grade of fuel, and use a quality fuel i.e. BP, Shell, Chevron. You will not gain much by using a higher octane in a vehicle that specifies 87

Answer 4

depending on octane rating-i believe they're all pretty close- if your engine doesnt need the higher octane fuel you wouldnt see a difference "if your manufacturer requires premium fuel and you dont use it you could see a difference"

Answer 5

it depends on the quality of your engine we have sports/ tourer bikes and they must have ulitimate for the best performance

Answer 6

Yes.

Just because I said it is.

Answer 7

yup

Answer 8

Yes it is.
