Protect lubricate , extended life of fuel system
Abusing price, I guess because they know it works, I would recommend opti-lube even though I have use it only a few months, I get better mileage and give me peace of mind, knowing that it is protecting my expensive injection system by lubricating it’s internal parts extending its life . Recommend by the Oil Guru in YouTube ( I own a Diesel truck with a Cummins engine 6.7 )

Works good for me.
I watched independent lab studies done on various brands of diesel fuel additive and this was the one that came out on top. Most additives are probably just as good but why buck a lab study.

Best additive I have found
Just purchased my second gallon Does everything I wanted engine a little quieter and somewhat better fuel mileage if test results are true the fuel pump is getting more lubricant and should last longer I have tried several different brands and this seems to be the best

My 2001 Ram 2500 24 Valve Cummins seems to really like this additive but for a total cost of $155 ...
I am only giving it 3 out of 5 stars because of the total cost I ended up paying...the cost of the product it self is reasonable but since I live in Canada the shipping cost was very high and then I got a bill in the mail from Fed Ex for another $42 for customs fees, etc. My 2001 Ram 2500 24 Valve Cummins seems to really like this additive but for a total cost of $155 for a gallon I definitely won't be ordering it again. I'll stick with the Power Service and 2 stroke oil mix I've been using for the past 10 years with great results.

Shipping is ridiculous
Love the XPD. But paying over $50 to ship a gallon to me just isn’t right. Need to find a solution for this please.
