NO MORE CRYING

I drive a 2005 silverado half ton pickup and pull a 23 foot trailer. Since I have added the dt550 to my engine and transmission my old truck doesn't seem to CRY as much and i have noticed an improvement in my gas mileage. I highly recommend this product.   Gloria

100 mores hours of racing

The first time I used DT550 in my KTM250 sx-f, it made a world of difference in how free the bike felt, it felt like a brand new bike. We used it in my clutch case oil and put some on my chain guide to see how well it worked and it dropped my lap times by 6 seconds. On top of how great this additive worked, we just recently rebuilt the motor and every bearing, every single seal and every gear in the motor could have taken another 100hrs of racing. and I am not easy on my bikes by any means. I even put it in my 94 Ford Probe and it increased my gas mileage by at least 8 miles to the gallon. I greatly encourage other teams and riders like me to find out how great this product is because it will save time and money and it already has for me         TRES

Truck no longer struggles

Since adding DT550 to my oil, I have noticed increased performance and power of my engine. My truck no longer struggles to get going. thank you G&H .           ROB

500 hundred over my 5000

Hi Harold. I've been a little behind on changing the oil in my impala lately 500 hundred miles over my 5000 my oil change. wasn't to concerned no warning lights came on. changed it at work today. less than a quart came out. I guess that DT550 is doing its job.    THANKS DAVE. 

Sept 29 Lucas Oil Raceway

crew chief informed us by adding DT550 to bearings on the axles and lubing the chain they went 1.6 mile an hour faster in the quarter mile. 


            thanks Tom for your input love to here it G&H                                                       

147000 miles

Added DT550 to my car with 147000 miles on it. have noticed my steering feels tighter like when the car was newer also seems like the car is running smoother and it runs pretty smoothly already with the Amsoil so its noticeable to me.

I LOVE DT550

I met you at the I-96 Speedway this last summer. I remember walking up to your display and then being selected to add the weights to the friction machine. Like most people, I was skeptical at first,but when I saw what DT550 actually could do, I was shocked and impressed! I remember handing you a 20 dollar bill and buying some right on the spot. Since then, I have convinced my mom. my step dad, my grandfather, my brother, my dad and several others to buy some as well: people  all over Michigan and even out here in Utah and Nevada.

I LOVE DT550! My wife and I drove my car back from Michigan to Nevada with dt550 in the crank case and I could DEFINITELY feel a difference. as soon as we got back, we ordered some more to add to her car and three other cars of people I know. In my car, if its made of metal and moves, it's got DT550 in it: crank case, transmission, differential, engine etc.

FRANK'S TRANSMISSION. Coldwater mi.

Just finished a 1935 Rolls Royce transmission. All assembly lube is DT 550. Thanks for such a great product. JOHN MILLER, FRANKS TRANSMISSION.

SURE MISSING OUT

Thank you Greg and Harold for the DT550. I put it in my 2018 Mazda CX-5 yesterday and I was amazed at the difference in the way the vehicle runs and rides. I'm not sure what is in that fluid, but anyone that doesn't use this additive is sure missing out. I will be spreading the word for you and I would expect you to here from me again very soon when I place more orders.                 GOOD STUFF !          Jim.
