[QUOTE=pk4144;1739688]While I like this forum, I particularly love three types of threads: oil, additives, and tires. It's like the Kardashians on TMZ: grab the popcorn and sit back.
Ha Ha, +1 on that!
I'm of the opinion that, just like oil, not all fuel brands are created equal.
Since I don't generally frequent one particular brand, I'm in the Techron group for reasons already stated.

It will vary by location and its minimum government regulation. Some places may be allowed to not add any additive package whatsoever.

As concerned as many people here seem to be about taking their car only to a dealer for oil changes so they don't "void the warranty" I am surprised that they are more than willing to risk "voiding the warranty" by using fuel additives. Even though Jaguar specifically says they should not be used in the Owner's Handbook.

Interesting stuff, as always. More thoughts/questions:
- I've never heard of states regulating anything other than ethanol levels in fuel. (In CA, the price per gallon always jumps a little at the beginning of "Ethanol Season.")
- I will say that on my cross-country drive I noticed that some states stock 93 octane premium, while states like CA have 91 octane premium.
- On my XKR (The Car That's Had Much Work Done), I had an injector go bad at 18K miles. As someone posted, I think I probably got beat up on a bad tank of gas.
- I try as much as possible to stick with Chevron and Shell. I have always understood that the detergent levels in these brands are high enough that additional additives like those black bottles of Techron are not needed. Is this not the case?
- finally, has anyone had this done? Is this recommended?

Detergent levels can NEVER be high enough in gasoline due to logic.
Look on the bottle of techron- its says use only every 3000miles. 2 bottles may be required.
They cant afford to put 2 bottles in gasoline and still compete with 'Bumpy's Gas' around the corner. With lower overhead no less.
More importantly how can they safely add the right amount given the driving diversity. One guy drives 50 miles a week, and another like you can do 5000. If they add enough to clean your car in 500miles, the guy driving 50 miles will take forever and you would have 10x the amount in your crankcase.
But I digress. The notion that fuel can be a detergent is misleading. It is a hydrocarbon that leaves a nasty gummy residue. At best that buildup can be retarded somewhat with pump detergents. Here is an image that folks dont often see. This is from a truck. Now ask yourself what gasoline was this guy using. Those 2 rectangular ports is where the gasoline is sprayed.

Looks like Hocus-Pocus to me. Another "elixir" for the suckers.

Hardly. Pull a spark plug and snap a pic with a bore scope, then use a bottle and check it again.
Especially beneficial on direct inject engines - (5.0). Land Rover is recommending it now, as Cambo indicated in post #19. Same engines, no? The manual also says the transmission is sealed for life. The oil recommendations have been modified since 07 as well.

In USA its naively foolhardy to believe that minimum standards are set for optimal consumer benefit.
No its the minimum amount of nutrition processed cardboard has to provide so as not to be a total scam. Its to protect honest cardboard cereal manufactures by creating a barrier to entry.

BK or similar Induction service absolutely works, performed by several Jaguar dealers.
Its better than and different from Techron, it cleans the intake valves.
Is it necessary on the 5.0? I dont know, I dont believe anyone does due to limited number of Jaguars with substantial miles on them.
Time will tell. On most other direct injected cars, heck yeah- sometimes its the only solution before physical dismantling and cleaning of the intake.

I think it is quite a leap to use this bulletin to support recommending a bottle of Techron in the fuel tank every XXXX miles is good as a preventative measure.

You cant pay for humor this good.
Regarding EPA detergents minimums:
The large auto manufacturers fought those minimums, citing 5-times more detergent was needed.
They started their own standard called Top-Tier.
Costco for many years did not comply (they dont have to) Now they have 5x detergents required by EPA.
Did someone say more is NOT better.
And how about that EPA- we were paying them to test for diesel cheating and college kids discovered it for free.

Land Rover recommends BG 44K Power Enhancer Cleaner to "... be used in the first instance in an attempt to cure a suspected ‘clogged’ injector (misfire DTC maybe stored) rather than unnecessary replacement ".

There are certain principals in Law that are as good as engineering truisms.
Look how many known facts you ignored to advance to a position.
Categorically:
Jaguar acknowledges there is such a thing as Poor Fuel.
Further acknowledges there are several repercussions to poor fuel
Their injectors can get clogged by poor fuel.
An additive is necessary to remedy the situation
Acknowledgement that Additives work
Admission that they left that all out of the owners manual.
Now we may proceed with our suspicions. However Jaguar's admissions puts doubt on the disbelievers.

So if they used Techron in the strength that actually allows it to clean the piston heads the following would happen: the guy that drives 1000miles a month, would see cleaner pistons and more power. The guy that drives 5000 miles roundtrip NY to CA would endup with 1quart extra oil in the crankcase. And he would sue one of the wealthiest companies in the world.
Absolutely correct.
If its mixed at a ratio of 1qt per 100gallons of gas at the pump: the guy driving 5000miles or 250 gallons consumed will run 2.5 qts of techron through the system. The guy driving 1000miles or using 50 gallons will only get 1/2qt of techron. So they play it super safe.

It seems that you enjoy embellishing your posts with stories, personal opinions and asides that attempt to regale the readers rather than simply stating facts.
