I buy this and once in a while the smaller bottle for a friend who absolutely loves it! Not much else I can say as I do not own a diesel anything...

I like the Cetane Boost it gives me noticeable extra power when it comes to towing. My Kubota tractor would always bog down in heavy snow and now it walks right through it. I highly recommend this product.

I am using this product in 2 older diesel engines, a 1984 Toyota Landcruiser 3B diesel with 520,000 km and a 1992 Dodge with a 5.9 ltr Cummins with 230,000 km. Mixing for a 7 point increase has given the Toyota a "seat of the pants" felt increase in power with overall fuel mileage up 1 mpg. The Dodge always had good power but with a 7 point increase mix I have gained a gear on hills and overall mileage is up 1.5 mpg. all while moving 5.5 tons of truck and load. Overall I am very satisfied with the product.

Vehicle: 2008 Ford F-250 XLT 4X4; 6.4L diesel. Work and play. 105k miles. A new engine runs about $17K. I believe in ultimate lifespan (500K miles) and I use Amsoil products to achieve that goal. The Cetane Boost delivers both a smooth and more efficient power, plus improved mileage. Ford recommends No.1 diesel fuel, but that is not available where I live. Cetane Boost brings my engine to the performance level I did not receive factory new. Does it add to the cost of operation, yep, but you get what you pay for. Remember that $17K mentioned earlier? You can buy a lot of engine care for a fraction of a new engine.

I use every tank full bin using a little over a year

Mechanic recommended this after 3 Bad Injectors, although all 8 where replaced . Used a bottle at every fill up and still lost another injector !
