My Grand Marquis is wrather stingent with gas mileage increases over 23 mpg (via dash computer). In fact its never gone over 23. I've tried switching different grade oils (10W to 5W) and nothing. Tried octane increase, lead subsitutes. It did nothing and the way the computer is set - it never would've. I put Tufoil in and BAM! jumped to 25!! As promised the car turns over faster also. Performance didn't change but this oil additive is a must and i have yet to read anything bad about it. And although it contains teflon, the formulation is so small that there is 0 chance of oil filter clog or for oil ports! This is not Slick 50!! I have never been happier with an automotive additive

I've been using TufOil for about 17 years. First on a Nissan Sentra that gave me about 205,000 miles before I gave it to my mother. She rode it for a bit longer. The car was put to rest eventually due to body rust -- NOT engine problems. I am currently driving a 97 Nissan Maxima with 248,000 miles! Again, no engine problems whatsoever! The car is starting to suffer from loose suspension, etc., but the engine is in EXCELLENT condition. It doesn't burn any oil, no knocking, etc. The engine runs extremely quietly. I expect the engine to last at least until 300,000 miles -- I hope the body can keep up! I believe this product has the same basic principle as Slick50. Unlike Slick50 where you add a quart every 50,000 miles, you add 4 ounces of TufOil with each oil change. The most important thing for long engine life is NEVER, NEVER, NEVER miss an oil change! Always do them on schedule. TufOil just makes your oil behave like super-oil. My trick, while a bit expensive, is that I change the oil every 4,000 miles (easy to remember: 4K, 8K, 12K... 244K, 248K), plus I only use synthetic 5W30 oil, plus I always add 4 ounces of TufOil. Maybe it's a bit excessive, but my 248,000 mile Maxima still has all the pep it used to and purs like a kitten.

I started using Tufoil after reading about it in a NASA technical publication years ago. In those days I was most interested in car performance, and Tufoil delivered, reducing internal engine friction enough to make a difference when the light turned green. When engine temperature and longevity started to mean more to me than snappy performance at the stop light, Tufoil was there again, bringing the temp gauge on my conversion van down significantly and letting me carry and tow larger loads without overheating. Now, fuel prices are a top priority, and again Tufoil earns its keep with every extra mile its friction-reducing properties wring out of each gallon of very expensive gasoline. After emptying a bottle of Tufoil into my car's engine (I use one eight-ounce bottle at each oil change) I refill the Tufoil bottle with the oil for my lawnmower, snowblower and other 4-cycle gas- powered tools, then use that Tufoil-enhanced oil when those need maintenance; they also run cooler and quieter with Tufoil. Years ago, oil additives were widely discredited by mechanics as "Snake Oil." Tufoil is different -- NASA says so, and experience proves it. |
| BEST TREATMENT I'VE EVER USED 20% INCREASE IN MPG AND IMPROVED HP ON 170K TRUCK. |
| I had a 1991 Chevy Euro Sport lumina... I put three hundred and ten thousand miles on it before some one rear ended me. It was still running good because of Tufoil... better gas mileage, faster starts and cold weather protection... I'm using it now in my Olds Intrigue ... better gas mileage right away... highly recommended. |
| Oh yes, fast shipping. "Tufoil" is the best kept secret. Thank you. |
| I have been using Tufoil since the early 70's. I have a 1953 Ford tractor which without rebuilding the engine has gone from bearly functioning to like new power due to the effects of a diet of Tufoil. I have had the tractor 13 years, it went from a big smoker to burning no oil, from weak to strong! |
| Engine load went from 51 pct. to 47 pct. at 75 MPH on test track. Good product. |
| My last order only took around 5-6 days to arrive here in Guam. Thanks again for all your help, it's really great to purchase from your store! |
| Your online store (tufoil.net) has the fastest shipping and the best prices. I love this product which I use in my duramax diesel. It cranks right up in the cold and I enjoy better mileage using tufoil. |

I have been using Tufoil in my truck since I bought it back in 1997. I currently have 122,000 miles on my Diesel Motor. I can't believe that it still runs like the day I bought it. I am hoping to get 500,000 miles out of the motor. At this rate it doesn't look so impossible. Keep up the good work. I'll talk to you at 500,000 miles
THANK YOU TUFOIL! |
| I have a 1987 Acura Integra on which I have used Tufoil every oil change, changing the oil every 3500-4000 mi. The car now has 322,000 miles on it with no major engine work! I have to attribute this to Tufoil's lubricating qualities as the car still runs smooth & quiet. I recommend Tufoil to all of my automotive buddies. Keep up the good work. |
| I have NEVER added any additive of any kind to a car or pickup that made as much difference as Tufoil. My engine in my P.U. and van just "PURRS" like a kitten. It really makes a difference. I have gotten at least 8 more people started on Tufoil in the past few weeks. (Thank you.) The stuff sure works. |

I tried TUFOIL upon recommendation from my Father-in-law in my 1986 Ford Escort with 89,000 miles on it. I was reluctant to spend the money and saved my receipt so that I could send for a refund when I 'objectively' decided that it made no difference. After using TUFOIL I did notice the car ran a bit different but it was a tough call on whether it was running "better" or not.
Until, my wife was driving the car and the engine light came on. She knew that it meant trouble so she turned around and drove home, 13 miles, with no oil I was to find out later. A bolt to one of the timing pulleys had loosened and drained the oil. I fixed the problem, put 4 1/2 quarts of oil in the car and it runs fine today. Needless to say I put 4 oz. of TUFOIL in as soon as I could and strongly suspect that nothing was ruined because of TUFOIL! I will use it in all of my future vehicles! Thank you for your time and your product. |

Specifically regarding my 91' Grand Prix and my 89' Grand Am, both with Quad-4 engines: With Tufoil I not only got 3+ mpg increases, but more importantly, the operating temperature of the Quad-4 aluminum engine runs a minimum of 15-20 degrees cooler. While not using your product, I had to replace the head gaskets on both cars. The mechanics attributed my trouble with both aluminum engines to excessive heat, aggravated by poor cooling-fan operation, I think your product is incredible. I will never trust my Quad-4's to any other product. The much improved temperature regulation on my cars is worth almost any cost of your product. Please don't increase your price just because I said this, however I plan to use Tufoil from now on.
Thank you for your product. |

I have been a Tufoil user since you started -- A lot of years. In that time, I have been able and happily able, to turn dozens of people on to your product. Most of my purchases go as gifts, pushing people into using it permanently on their own.
I operate two Barracuda cars, a 1968 Fastback and a 1969 Convertible. Both are 318 CI V8-powered vehicles, American-made for American conditions. Never has it been my wish to give up these cars and I do not have to, becuase with Tufoil it is just plain impossible to wear them out. The engines on both cars have been lavishly Tufoil treated form many years, and they run and start like new. My wife's 1989 Dodge Omni was Tufoil'ed upon purshase, and is a quiet and smooth running tribute to truly effective lubrication. Tufoil is especially necessary in these little cars with high-revving engines and without the treatment a relatively brief life for these engines is a certainty. I have discussed the use of Tufoil with veteran Marine engineers on big ocean-going ships. They are of the opinion that treatment of the ships' total lubricating system with Tufoil would result in perceptible fuel savings and smoother acceleration. However the steamship companies tend to be ultra-conservative and little has yet been acheived. Were it to be found that the ships' economy could be improved even a couple of percentage points, you would be selling thousands of drums of the stuff.
I still enjoy showing engineers and others Mr. Reick's little adventure with the Dupont Big Shots in Delaware, where they had to give you a special letter saying you were right. |

Thank you for Tufoil. My '79 Buick just rolled over 252,000 miles on the original never rebuilt engine. I now use 12 oz at each oil change as she is getting a little tired. Thanks, Tufoil. |
| I must relate my experience with your Tufoil which I have used in both the engine and transmission of my 1980 Saab 900 since it was new. The car has just reached the 260,000 mark. |
| I have a 1983 Buick/LeSabre Ltd. with 213,000 miles plus and still going strong!!! It still runs incredibly smooth and quiet... as good as any brand new engine. I attribute this extraordinary performance to Tufoil. |
