StanadyneWinter 1000 16oz Pint Bottles - Pack of 4 - Part # 38574

This stuff works, for sure. We had a couple super cold days here last winter (-20's F without windchill, -50's F with windchill) and my truck started right up with just 1 or 2 extra cranks on those days (with the block heater plugged in of course). But this stuff kept the diesel from gelling up. Truck ran fine once it warmed up. No fuel issues.

It did exactly what I expected. No gelling and no engine side effects

Have not used and wanted to return but it is considered a hazardous material so I can't return. My fault, I guess. I'm not slamming the product just wanted the performance formula because it has better lubricating qualities.

Use Stanadyne all year long - this is great for winter!

Extremely cold this winter in the Northeast! Stanadyne Winter 1000 did not disappoint!

Does what it says

👍

Great product have used it for several years in my 2500 diesel.
