Hello everyone, was wondering if any of you had any experience with lucas fuel treatment & if you would recommend it in a brand new engine (1500 mile)? Engine is not stock it is a crate 350 with some mild upgrades & is of course fuel injected. Just would like some feedback from any who have used or have any info. Thank you very much!! JD

I have used it with great success but would see no need for it in your case.

So it is for engines with more miles on them ? Thanks for response!!

In new or old engines, most fuel "treatments" are useless. Use a top tier gasoline and you'll probably never have any problems.

Snake oils, whiffle dust, mouse milk and this are all about the same. Separate the chump from his money. In my area, my injectors get dirty just like any other area from fuel. I just have them professionally cleaned and tested every 3 years. Dumping these potions and lotions may clean it or may not. Sending it out will and testing is done.

I agree, but dont see the need for every 3 years. Id say if you start experiencing problems then send them out. Id rather put my money into a quality fuel filter then mess around with fuel system cleaner. I guess if I had to do something Id run berrymans B12 chemtool in a tank of gas, Ive had good luck with it in carbureted motorcycles and ive cleaned parts with it and its pretty potent stuff.

Don't know about their fuel treatment but their oil stop leak stopped a bad leak in my 89 a year and a half ago and it's still not leaking a drop.

These cleaners just flush all the crap to the filter or beyond to gather at the injectors own filter baskets..

Here is a graph of my own 150k mile Rochester injectors off my '87 when I sent them off for a refurb. New filters and seals fitted..

In the lower image, 1 and 5 good, ..others bad!

Thing is, the ECM will compensate and these changes occur so gradually, it is hard to experience problems till it is really FUBAR. I had a filter basket that was collapsed and couldn't tell the difference because while it impeded flow a lot, relatively, it was only 1 cylinder and hard to tell. I came upon 3 years because of testing. I have occasional access to a flow bench. I have had diesel injectors that didn't make any difference in the feel give 1 plus mpg gain after they were cleaned and balanced.

I tested them before I send them out several times and about 3 years, there is some difference in the flow. Ideally, you want everything to flow at the same rate. I just sent a set of 6 injectors out from a car I got with 100K. IIRC, there was about a 30cc difference from highest to lowest which came down to a 1 cc difference after cleaning and testing.

aklim

Not all do. Some just lighten the wallet.

The spray pattern is one thing but your flow rate is also lower WRT the "after" and uneven too.

Precisely what problem are you trying to "fix" on this new engine?


The additive package in plain old gasoline is BETTER THAN GOOD ENOUGH. <Click the link.

Unless your engine has developed a specific issues that requires extra detergent to repair, then adding these kinds of additives is nothing but a waste of money...or it's fixing a psychological issue; not a mechanical one.

I do use Top Tier gas when possible. About 90% of the time. In about 3 years, I get a loss of 20cc from after.

Get a C5... your tune will change.

I see no need if your fuel injectors are new. Unless you have a C5 and need to clean the contact on the fuel sensor in the tank.

Silver96ce

Chevron Techron is supposedly the best at getting fuel senders in the gas tank to start working again.

2ooo-C5

Yep... but it is one of the snake oils he is referring to.

aklim

However new your injectors are today, they get old and dirty after a while. I have new brake fluid today but in a couple of years, it gets old and dirty and needs to be flushed out.

aklim

I don't have a C5 but I have heard those stories for other cars too. Dump it in and maybe it does something, maybe not. If it were my car, I'd pull the sender and check it first and see what the issue is. If it is corroded, probably toss or try clean the metal strip or whatever it is with something abrasive. Years ago, I did do that on another car, can't remember what it was.

I've tried a few brands over many years and the Lucas brand is the only one that actually showed me any improvement. I tried in in my higher mileage 2002 Optima, that I had been using for long distance service calls. I went on two long highway trips about three weeks apart. Before the second trip I put in a can of Lucas fuel system cleaner and I got an amazing 4 mpg better gas mileage on the highway on that multi tank trip. I was even hauling more luggage in the trunk of the second trip too. The can of Lucas was the only thing I did different, so I have to think it actually did something to the fuel system/ injectors.

Seems like a pretty decent test, but those results are pretty incredible. If I got results like that, I might buy a 55 gallon drum of the stuff! I tried some BG cleaner in my commuter because we had some at work, so it was free. My gas mileage went down.

aklim

Dad filled up at one place and got 5 mpg more. Wind had an effect especially when hauling that 38 foot gooseneck. One could say the only change was the brand of fuel used. Only way to really see is if it can get a consistent reading from then on since the dirty injectors are cleaned or so we assume. Best way is to get a set of injectors with 200K, test it, simulate a run with the proper concentration in a tank of gas and retest. I have checked FIC's work and we get about the same numbers with the bench tester going in and coming out. On my 606 diesel, when we did that, there was a consistent gain of 1 plus mpg instantly when we measured it over a 20K timespan.
