Noticeably it helps in several ways.
Can’t speak highly enough about this product. I’m new to Diesel engines , about or not even 7 months. . Definitely notices several things. 1. Ran quieter a little , Not a bunch yet noticeable. 2. Ran cooler also. Having Cetane in it makes the knocks Quiet a little in all RPM range.. 3. Starts energetically anyway, so In near freezing or 95 Heat it starts in about 1-2 RPM’s very efficiently. Definitely noticeable in these points, I HIGHLY suggest use it.

Recommended for older diesel motors
This product is recommended for older diesel engines. My 2003 Silverado 2500 HD has been using it for the last 10 years and the fuel injectors have been going strong ever since. I compared gas mileage with and without the additive and it looks like it’s better by 4mpg better with it. This was a 2 month test tracking mileage and fuel used with and without the additive. A rudimentary test but good enough. Most important was not having any engine problems in the past 10 years. Not bad for a 22 year old 3/4 ton truck with 200k+ miles.

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 )

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.

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.
