Empty XPD 4oz Bottle

These have to be the best 4oz empty plastic bottles out there. High performance quality and they match the XPD product line perfectly. I swear they added 2-3 hp to my 2001 Dodge Ram 2500 Cummins as soon as I started using these in place of the no name brand empty plastic bottles. Highly recommended.

Currently mixing boost and xpd with great results. I feel i did not need as much lubrication as xpd brings alone and boost uses less additive per gallon for $$ savings. Kind of my idea of POWERSERVICE PLUS CETANE BOOSTER, but with higher quality XPD PLUS BOOST. I do average mpg slightly higher with just xpd but the mixture gives me quicker detonation during injection (performance) and more of a jerk during downshift acceleration (faster response) . Application is N57 BMW diesel.

Awesome product. Recently purchased a TDI Touareg and I must say this stuff made my engine quieter. It used to have this weird clicking noise but it doesn't have that anymore. I am quite impressed with this additive.

Love this stuff. Definitely always mentioned as one of the top fuel additives in modern diesels

getting 21 MPG in my lb7.

I have 2013 Volvo D13 engine and I put that stuff in it made a really big difference engine running smoother and gas mileage is much better so it is a really good product I recommend a two dollar people.

It's hard to know if diesel additives actually work. I've tried one other brand and my 15 Chevy Duramax seemed to go into regen mode quite often. It doesn't with OptiLube and I found a test that said it was one of the best. So, for now I'm going with it.

Opti Lube keeps my Diesel Running strong and clean. Highly recommend over the other brands.

Trucks runs smoother with continued use of this product
