Yeah I don't (spark)knock what may work for another I just stick with what I get results from lol.

 

OK, I will bite. I am pretty sure you, me, others get "effect"!

What do you suppose the mechanism for Lucas injector cleaner to "bring the MPG up"? And I assume you mean "down". Just wondering. And by the way, I am ashamed to admit that have poured Lucas and other snake oils in to chase what seemed to be a dirty injector, and I could tell no difference. It turned out to be a vacuum leak.

What happened with all the anecdotal evidence of the wonders of 2 stroke oil in the fuel? (TC-W3) Remember that one? It took this and a bunch of other forums by storm. Not so much any more. I guess it rejuvenated all the old engines and isn't needed anymore. And Brown's gas... You had to watch out for the fire hazard from the gasoline pouring out of your tank.

Show me some data, then I will believe.

 

Lubes & cleans deposits from the injectors is all I can plausibly tell you, maybe improves the integrity of the modern cocktail, suppliers call gas. I have no state of the art lab here, but what I do have is well over a decade of using it & have had MPG improvements on nearly every vehicle I've used it on. Some were remedied of the dreadful spark knocking & rough idle as well.

Been on Lucas fuel treatment & oil stabilizer since my days of having a old school Mitsubishi Diamante I had turned into a twin turbo with bad lifters that smoked like a dragon out the rear from blow by, Added Lucas oil stabilizer I drove the wheels off it for 2 more years(@ 250,000 miles to boot) lol. I don't bother w/ the oil stabilizer any more but back then I was a band-aid kind of car owner lol.

My data was simply more miles to a full tank of gas after adding.

If it works, I use it, simple as that.

 

If something, in this case, fuel injectors are surgically clean, they can
get no cleaner and therefore can not operate any better.

However, if fuel injectors are dirty, then cleaning them makes sense:

Therefore, it works for some people because their vehicles have room
to benefit from it. It does not work for those few who seem to have
surgically clean fuel injectors year after year.

Lucas is a particular brand and chemistry. It could be better, or worse
than the other favourites in the category.

Do I use fuel injector cleaner? No, I don't feel the need. When I am
moved to do so, I dump some TC-W3 into the fuel tank.

Would I tell someone else not to use fuel injector cleaner? No, I
believe it can be useful.

Unfortunately, as compared to other automotive forums, including
other Jaguar forums, this forum has by far a larger proportion
of posts dedicated to telling others what they should do under the
guise of debunking "myths". I see no value in that behaviour and
find it offensive at best.

 

Tell you what, show the data that it does not work.

 

Lucas fuel injector cleaner is nothing but light oil and a dose of detergents similar to those already contained in pump gas. You're getting more detergents in a tankful of gas than probably 2-3 bottles of this or any similar snake oil.

 

That is simply misapplication and misdiagnosis.

The same reason why using a hammer on a screw
seldom works as well as a screwdriver.

 

On older cars this wasn't the case from it's day 1 use(cleaner fuel w/ additives etc.). Nowadays I agree all the detergents are present. As I previously said, my faith in the product I spoke on was accrued over nearly 2 decades.

To each their own, Godspeed.

 

Mr plums:
I am truly sorry you are offended by an attempt to debunk "myths". Maybe what you are offended by is someone calling you out on statements you make as fact, when they are only your opinion. Folks come to a forum to get ideas for their own use. I believe it is perfectly justifiable to offer alternate positions to posts that have flawed facts. Maybe this forum has a greater preponderance of folks offering myths as fact OR maybe it has more folks with a keen eye for BS than whatever you are comparing it to.

 

I use the Lucas product, dump it in the filler port just before a fuel top up - that way the fuel washes all the product into the tank.
Like most on here I suspect I am quite dubious about any "performance enhancing" product, although I can honestly say that with the Lucas product my mpg did improve (on a 250 mile run I got 35+ mpg (uk) which I've never had).....

 

Cars have changed tremendously in the last twenty years and even more so in the 40ish I've been playing with them.

What was appropriate and effective back then is very different than today.

 

Touche' sir.

 

Nice to see a little warmth. Things were getting boring on here . ;^) I'm an STP fan myself, but then I'm a relic myself.

 

I think we are all old relics -- that's why we drive these old Jags. Well maybe not the guy who started this latest 'discussion.'

 

Yep, we are!

 

This thread inspired me to order a can of BG44 from Amazon lol.

 

I wonder what prompts owners to believe that their car has developed clogged injectors and that it must be treated with and will be 'cured' by a myriad of aftermarket supplements. Is it the power of advertising? Following what dear old Dad did on his '32 Pontiac? Peer pressure? Conspiracy theory?

If I were a gasoline manufacturer, I'd find out what these miracle chemicals are and add them to my product at the refinery. Then my advertising campaigns could boast that my brand cleans engines, improves mileage, boosts power and results in more half-naked super models around my pool.

Maybe not the last one, that's for beer.

I can't remember the last bona fide case of clogged injectors or carboned up combustion chambers on this or the other car and bike sites I visit. Lots of people who *think* they have a problem though.

They stole my idea! The b*stards!

 

Actually, I think Chevron had it twenty freaking years ago: Techron. BMW was sold, recommended using Chevron when available.

As a Chinese friend of mine pipes up when I blast his wife and mine for believing in ghosts: "Jim, what harm does it do?" My point, use if you want to, as long as does no harm. But sometimes it burns valves!
So sparingly.
