Default premium unleaded fuel only

While working on a sticking fuel door latch, I peeled off the
fuel sticker in the filler well.

It said:

Premium Unleaded Fuel Only
That's an exact quote.

I avoid ethanol, but for the sake of accuracy, it didn't say "no ethanol".

I regret not taking a picture before trashing it. It would have been useful
for those times when certain people want to argue that regular is just
fine.

Post the picture ... end of debate and demands for "proof".

It was (and is) my sole responsibility to say "no ethanol", I will look if the sticker is still on mine and post the picture if it is.

I'd like to know what octane level, measured in either the RON or AKI rating system, meets Jaguar's criteria of 'premium'. We're all aware that the fuel manufactuers have no set standard.

I've been putting around Europe for the last few weeks in a Skoda Octavia, a very good quality motor car. The sticker on the fuel door says 'premium fuel only', which at most fuel stations means 98RON. The owner's handbook defines 'premium' as 95RON which is 'regular' grade.

Sigh.

No ethanol premium 92 U.S. Octane minimum. Anything else compromises performance and longevity. Ethanol = farm subsidy/price support for corn farmers.

Is this in the owner's manual or just more conjecture and opinion?

Cars (actually engines) built up to 2003 were never designed to burn anything with ethanol in it. By experience I can tell everybody it kills engines.

I'm very sorry. I didn't want to mess up this thread with my remark.

Vehicle Care Handbook, page 84 (Specifications):

"Fuel Requirements: Use only Premium Unleaded gasoline with a minimum Anti-Knock Index (AKI) of 91.

Oxygenated gasoline blended with ethanol (max 10%), methanol (max 5%), or methyl tertiary butyl ether (MTBE) (max 15%) may be used.

It is recommended that only fuels containing detergent additives are used in your vehicle."

In over 30 years of driving almost a million miles, I've never had any engine "killed" by E10. YMMV.

plums,

While replacing the filler neck gaiter on our '93 I made a reproduction label to replace the deteriorated original. I wanted to help ensure my wife and kids didn't forget and put regular in the car:

Welcome to Jag-lovers - Members Photo Viewing Page


Cheers,

Don

That's great! Alas I got another (nasty) experience using 10% of bio-ethanol or E10 as it is called.

Here in the colonies, there are states where 10%ethanol is the only gasoline sold. Virginia is a prime example. So, unlike France, we use it or let the car sit and rot. Just once, though, while in West Virginia, where one station had premium, 93Octane (US standard) without ethanol, I filled it: what a difference, ran much better.

And my owner's manual says 91 or better is the required octane.

Here in good ol' Oz we use the RON system and our fuels are thus:
Premium Super 98
Premium 95
Regular 92
and then of course there are the crappy imported ethanol mixes...E5 E10
I always use Premium 95,

yeah while ethanol is ntot very good in many places besides a few back woods part of texas and maybe a few other back wood areas, ethanol E10 is all that is offered.

It sucks, especially on my older cars, messed up my fuel fittings something fierce that was new then they switched over, all that work about $1000 in MBZ fuel stuff down the tube and had to redo it again for ethanol safe rubber stuff, some of it was hard as hell to come by for those years.


This car, not so much, still not the best, but no other choice. US been known to have some crappy gas over the years and when they find a way to improve quality of gas they find some way to flub it up in one manner or another. Firt it was just low quality finally get high quality they add that corn crap just to give rich farmers some money. And if one never been over seas they will never know the difference. But when taking car from the states then over seas and see the difference. It is very very noticeable.

I love how a simple post about a sticker turns into a random debate.

Yes I only use premium, and I only fill up at select stations that are Ethanol free so I do agree with the people here. Its just funny
