"You can add Diesel Tech magazine to the long list of testimonials as we're now believers in Archoil too.
"Improved fuel economy, smoother running engine and no issues with cold starts."
I have a '98 Toyota Rav 4. The check engine light came on and coded for EGR valve. I first used some Cataclean, which I had to
keep my new catalytic converter in good shape, but also said it could remove carbon deposits on
EGR valve. After using it twice the light went off for a couple of days and then came back on, by that time I had gotten my order of Archoil. Wow! the engine ran so smooth and
I run a 2012 f450 car hauler started using the fuel additive and loaded mpg went to 9.5 for 7.8 huge On the instant side unloaded my mileage with pulling an 8500 pound empty trailer I see about 11 1/2 miles to the gallon Cruising 65 at 2000 RPMs
I also added the oil additive the motor seems much happier smoother and quieter When running up long easy grades if I keep the pedal at 65 It just runs up the hill it’s six gear with no issue
I've been using this in my 2009 Ford F350 since I bought it a few years ago. I didn't find out about the frailty of the 6.4 engine until after I bought the truck. I'm crediting the use of Archoil to keeping this truck starting quickly, running smoothly and not needing the soot being burned out very often.
Hi, I used AR 9100 (Engine Treatment) and AR 6200 (Gas Treatment) together for my 2006 Lexus 400H (227,000 miles), Engine runs very smooth and is in great condition even on highway driving. However, I encountered very minor issues like black sooty smoke and gas smell for 30 to 40 seconds on cold start even after using Premium Gas. I tried popular brands of engine and gas treatments several times; but they could not prevent this sooty smoke and gas small; moreover, my SUV passed emission test too.
However, though not desperate, my intrusion was to add some oil additive to engine and gas to protect engine, transmission & catalytic converters in future. After through search, I decided to use Archoil. From day-1 of using Archoil, engine runs quiet, significant difference is seen after 200 miles of drive.
Significant difference what I noticed is that cold start that was producing black sooty smoke for few minutes after the engine start is vanished completely; In addition, gas smell on hand test is ceased too. Unfortunately other popular brands of engine and gas treatment could not prevent this sooty smoke and gas small.
I do NOT drive much; hence, I can NOT tell mpg increment and Cold Start is very smooth.
I highly recommend both AR 9100 (Engine Treatment) and AR 6200 (Gas Treatment)
This stuff works great I started noticing the injectors in my 1997 7.3 powerstroke started to quiet down around 70miles of driving after I added the archoil I'm sure of the miles because I reset trip odometer when I added it to fuel.
