TriboTEX for Diesel Trucks - Made in USA

Sale price $189.00 Regular price


Diesel owners don’t get left out in the cold here at TriboTEX.

We understood that diesel owners need a tougher formula to keep their engines running strong. Ready for much tougher conditions than your average Monday morning commuter. Diesels need extra protection for higher engine temps and pressures.

Luckily, our research team came up with a formula that performs. In the first 500 miles of use, you’ll see:

  • More power under the hood for that extra git-up-n-go
  • Better fuel mileage so you’re saving money on every trip
  • Strong noise reduction that you’ll be able to hear in the first 15 minutes

Applying TriboTEX is so easy, it won’t take more than 2 minutes during your next oil change. All you do is:

1. Warm up your engine after your oil change. Locate the oil cap under the hood.

2. Inject TriboTEX into the oil compartment.

3. Drive your car normally.

4. Drive 500 miles to feel the full effect.

5. Apply another coat after 40,000 miles (or your 10th oil change).

One application of TriboTEX Diesel treats engines with 8-13 quarts of oil. Compatible with all major engine oils, engine oil additives, and diesel engine types.

Great performance

I've used this product in my two gasoline engine cars and in my F-350 /7.3 Liter diesel. The big difference I noticed in the cars was, when it was time to change the oil, (5,000 miles) I checked the dipstick and the oil looked like I had changed it a week ago. I left it in and check it every 1,000 miles. So far, I'm at 8,000 miles and it's just starting to show signs of pollution. I'll probably change it at 9,000 miles. The truck, being diesel, can't be expected to remain as clean as the gas burners (and it hasn't) but, I went from about 11.5 mpg to 13.5 mpg. I highly recommend this product!

All in...

I have Tribotex in 4 engines. A 2001 F350 diesel (230k miles), a 2013 Nissan Xterra, a 2005 New Holland 30 hp diesel tractor (400 hours), and a 2012 CubCadet 23hp zero turn mower (300 hours). In all cases, there is less engine noise and easier starting. The Nissan had lifter noise on cold (

quieter engine after treatment

my engine sounds much quieter after the treatment. The mileage has not increased at all, but the knocking noise has diminished. Hopefully I will also get an increase in my mileage after a while.

Definitively, a good product

I made my first experience in a Volkswagen Gol and now in my Land Rover Diesel. After a week, I noticed a notable engine noise reduction and better fuel efficiency.

First impressions

I have a 1997 f250 heavy duty, 7.3 liter diesel with 300,000 miles,just a couple hundred miles since i use the tribotex. Definitely starting much quicker and easier, and may be just a bit quieter and doesn't quite smoke as much on cold starts.

Ford F 250 superduty.

Put the product in and ran for 200 miles. Did not notice anything different. Ran the truck this weekend for 500 miles in one day. Truck 2008 ford f250 started running quieter and stronger after 500 total miles on the product. Can't believe my own ears. Great product.


I do not see a improvement on the miles per gallon, however the engine is not as loud

First time using TriboTex

After an oil change I added one dose of TriboTex to my 2014 VW Touareg TDI. I have driven it for about 500 miles now, and noted a small improvement over my mileage by about 2 MPG from 23 to 25 MPG. Hopefully it will continue to improve after time, but the engine seems to knock slightly less than before, making it less noisy.
