Review: Works very well - An excellent lubricity additive. I use it in my diesel Land Cruiser which has twin 20 gallon tanks. One 4oz application (one small bottle) in each tank is a no brainer and restores fully protective lubrication to the diesel we run nowadays. Pump bottle is great - one squirt is one ounce - 4 squirts per bottle. Easy peasy. Happy customer.
Review: Opti-lube is the one! - Opti-Lube XPD tested very well in several independent test for lubricity and the XL product is mostly just a lubricity additive and water de-emulsifier so being a concerned Ford 6.7L owner, I use XL at the recommended higher mix rates to help try to ensure my HPFP does not grenade itself. Along with only buying diesel from high volume, quality fueling stations, keeping the tank mostly full, never letting it get below 1/4, draining a few ounces of fuel from my water separator weekly, (I also do 3 key on/off ycles afterwards to ensure the filter housing is full before starting truck as well) and changing both fuel filters at 15K intervals with Ford filters I feel I am doing my due dilligence to protect the HPFP. My truck is completely stock, emissions and all, I do not believe I have seen any gains in power, better mileage, etc. The only thing I do notice is a slightly different smell from the exhaust. Not an unpleasant smell, just different. 2011 F250.

### ⭐⭐⭐⭐⭐ Save your fuel pump
*by T***D on November 30, 2025*

This is a must have product for anybody that runs a CP4 fuel pump. The Bosch pump was not manufactured for USA diesel fuel standards. So if you want to save yourself $15k in repairs to the fuel system add Opti-Lube to your fuel at minimum every other tank.
