I recently used the Liqui Moly Fuel System Cleaner, I had a check engine light (PO420) for over 6 months, I was already planning to purchase a new catalytic converter, however after putting the additive in the full tank of fuel it made the light go away in less than 1/4 tank of running. The response and acceleration is restored. I used this product on a 2012 Jaguar XJL Supercharged 5.0. I highly recommend this product to anyone. I also used the oil additive to reduce tappet noise and it also did an awesome job at reducing the noise.
fyi, no matter the gas additive, check its effect on various materials. i soaked plastic, rubber, metal in B12 chemtool. chemtool was great at dissolving gunk and varnish. HOWEVER, it also dissolved/damaged certain rubbers and plastics. other cleaners, like seafoam, did not clean as well, but then did not damage materials.
Did you mix the products with gasoline at the reccomended ratios (one ounce per gallon) prior to soaking parts in them? Seafoam isn't harsh enough to damage anything, but as you said, B12 is if concentrated enough. That said, B12 has been a very popular additive for decades and I have never seen or heard of it damaging anything when used as directed, so I personally wouldn't worry about damage unless way overdosed.
@@averyalexander2303 no. it was a full strength test lasting only a week. i also tested seafoam and marvel mystery oil, both did not effect plastics and rubber, but where not even close to removing carbon as well as B12.
What exactly does "way too much cleaning" mean? Needless to say, once a fuel system is clean, there isn't any more cleaning to do, so nothing is going to get cleaner than clean no matter how many cans of additives you use. What's the real reason using Gasoline System Cleaner more frequently than once a year would be inadvisable? Will more regular use affect the engine oil, plastic/rubber parts, catalytic converter, etc?
@@iaimfortheeyes It likely is, but in that case, I think being more clear about the reason would have been a great idea so people don't make the wrong assumptions about or question the product's safety.
I saw on another website that valve clean is only for cars with non-direct injection. I have a BMW and I want to know if you can help me if it can be used with this type of direct injection cars.
Can anyone help? I have a 2014 cls 550 w218 I believe it's GDI. How long do you wait after using Proline gasoline system cleaner 1time a year to use D.I Jectron every 2400 miles? Or should I just use D.I Jecteon every 2400 miles? Can't find an answer anywhere for this? I do have a GDI engine. Thanks All
My experience is that using the direct injection cleaner, will do the best job on port injected engines, due to the content of the solvent "polyetheramine". I asked liqui moly, they tell me it can be used in port injection aswell as DI.
"...a 12-pack will take you through the year...." As will a -0- pack! (ask me how I know!) Why didn't car-makers think of injector-tip umbrellas?? DOH!!
It made my check engine light come on.I cleared the light, and now my engine keeps stalling,WTF so far, I checked the spark plugs and they are fouled from running too rich Now looking at the o2 sensors for 300.00 dollars .This product screwed up my car.
@SuperKanuuna And what do you think is a better car ? They are all pieces of crap.I keep mine and run it till they rust or fall apart.Because I do 99 percent of my repair work.What do you do buy a perpetual financed one ?
LM is one of the few companies that have fuel additives that make a substantial difference in the short term and long term. It isnt your typical gumout snake oil.
