Bye Bye Stanadyne

After testing the LubriGuard against Stanadyne the results with UltraGuard are similar. 2 to 4% better results with UltraGuard vs Stanadyne and at a lower cost per treatment. Will be full on with the Alliant products now.

Kevin A. (Regina, Saskatchewan, Canada)

Have ordered it before. Works great.

Thanks for taking the time to write a review Kevin!

Alliant Power Ultra-guard

Second order (5 Gal container) of this particular diesel juice. Used Raccor and Stanadyne for years prior, but have had no issues with, and do not see any loss or difference in performance with the Alliant Power Ultra juice.
My Brother and i share these orders for our trucks (05 Cummin's) and i also have two tractors, we have been ordering from Diesel Parts Canada now for 4 years and get delivery of these (5 Gal) containers in 2-3 days, to the door here in Ontario - "totally impressed" with the customer service and of course delivery from Diesel Parts Canada!
And the bonus is this stuff is way more economical than the Stanadyne.

I'm glad to hear that the additive is working for you guys. Thanks for your business.
