First and foremost I want ot make it clear I have no relationship with Opti-Lube or anyone who sells their product. I pay full retail price just like everyone else and am getting nothing out of this, nor do I want anything out of it. I understand fuel prices are already really high and any additive adds to the cost per mile, but for me and my situation it's worth it and I want to share this for those who are curious.

I want to try and keep my observations of my experience with Opti-Lube XPD as short and straight forward as possible so here goes:

I've used a fuel additive in nearly every tank of fuel I've put in my truck since I've owned it. I've been using Stanadyne Performance Formula at its listed treatment rate for nearly 120,000 miles, and it's always been obvious to me the difference in sound and quality of idle when I've had it in a tank of fuel and when I've not. I've tried to stick with the same fuel brand as much as possible even when traveling and use the same fuel station locally at every fuel up. I have been satisfied with Stanadyne's performance based purely upon this and think it's a fine product. That being said I recently became aware of the lubricity study that has been floating around for a long time, and noted that Opti-Lube was the second best performing product on the list. With my OCD regarding my truck, I figured I had better give it a trial run. I've been using the 1/2 oz/gallon treatment rate. I have to say I am shocked at the difference in qualitfy of idle smoothness, sound and consistency. Fuel economy is also up by .89 MPG AVG so far over two full tanks in very similar/consistant driving conditions/routes as my typical routine. At stop lights I find myself turning my radio off to listen to the idle, and I don't know how to express how much better my truck sounds! It's frankly shocking to me. While driving I have been hearing little rattles and sounds from various parts of my interior trim that I have never heard before becuase they were apparently always being drowned out by the sound of my engine running. Seat of the pants performance also seems to be improved, my turbo seems to come on sooner/faster (I realize this is meaningless conjecture - but it seems so apparent to me that I feel I should mention it).

I've always tried to take as meticulous care of my entire truck as I can, so I am very surprised that there seems to be such a benefit from using this product. To each their own, and I respect everyone's choices when it comes to what they want to feed their trucks, I just thought I'd share my own experience. Thanks for listening.

 

Hello and thank you for taking the time to leave this feedback. Your results are what we come to expect for our customers. This is why we are true believers of Opti-lube. The president of Opti-lube wants to send you some swag for your time. PM me your address please.

 

@Bitterroot Diesel I did not realize you liked the Opti-lube product. Do you recommend its’ use to your customers who purchase injectors?

 

Yes, we are a dealer and they are a great family run business!

 

CMRML, based on your location in the United States, you may see similar results at a lower cost per gallon/ounce by using Opti-Lube Summer+ blend. The Summer+ blend does not have as much "water demulsifier" and no "anti-gel", but is equal to XPD in the other three categories.

According to the Opti-Lube website:

• Opti-Lube Summer Lube +Cetane Diesel Fuel Additive: $59.89
• Opti-Lube XPD All-In-One Diesel Fuel Additive: $64.93

At a savings of $5.04 per gallon, that might not seem like much. Although, if you consider you plan to use this product long term, that is a lot of coins. Once I purchase new injectors, I plan to run Opti-Lube Summer+, but I live in north GA.

Current chart is below:

Where did you purchase this happy juice at?

 

I buy and use the XL since I really don't need cetane boost or any kind of winter protection where I live. Just trying to keep my injectors happy for as long as possible. I do keep a bottle of boost on hand for when I travel out of state.

 

Thanks for the info Sous!

 

I purchased direct from Opti-Lubes website. Turns out Bitteroot sells it on their website though too.

 

I also decided to start running an additive for the extra lubricity. XPD is very pricey. I ended up running a 50/50 mix of Summer & XL. It should give very similar lubricity and cetane improvement as XPD at a fraction of the cost.

I’ll just add in some cheaper Power Service winter treatment for the anti-gel if it’s ever needed. It’s rarely driven in the snowy months anyhow.

Mixing into an old large Sta-bil container which has side markings to help during mixing and a squeeze cup for easy measuring during fill ups.

Running it in the truck and tractor with no noticeable change in engine noise or performance. I do believe in the “hidden” lube aspect so will keep running it for now.

I purchased the OptiLube from a FTE site sponsor and got 4, yes FOUR separate emails wanting me to purchase “warranty coverage” for the product. I was more than annoyed at this marketing tactic on a lubricant.

 

I've been running a 50:50 mix of Optilube and XPD and Stanadyne Performance for years but I am just about out of Stanadyne and I am planning to run the Optilube only, XPD when we travel in Winter and I'll probably get some Summer blend for the hot weather. I use this in all 3 of my diesels.

 

Out of curiosity what treatment rate are you using? I use the higher option at 1/2 oz per gallon. Your change in product line combo sounds like something I will try too, who doesn’t like saving some coin? I do drive in some cold winter temps, but not daily so I like your strategy with only using the anti gel optionally. Sous made a similar suggestion both of your logic seems good.

I imagine results will vary for everyone, based on a LOT of factors, I just wanted to share my experience for others to consider. I think it’s great to hear yours as well RacinJason, so thank you for sharing them. I haven’t experienced the emails like you, but if I had that would certainly not be something I’d want to occur.

I think that the XPD product is worth a try and then it will either work for people or it won’t, but I hope it does if they try it, like it’s been for me. (I can’t speak to their other product lines besides XPD as I haven’t tried them)

 

Thanks for posting. Reviews like this are always helpful. I've been thinking about switching to Optilube as well, but seem to always end up with what ever I find at tractor supply instead. I think it's usually Stanadyne, don't remember which formula.

Little south of you here and I've been meaning to do the same. Unfortunately, I only seem to remember it when I'm at the pump filling up and that hasn't happened much here recently.

Down here I'll almost never need an anti-gel, so that's what I plan to do if I can ever remember to order some before I need it. I'll use so little anti-gel, I probably won't even use the Optilube stuff. I'll probably just get a locally available anti-gel and mix it with the Summer+ when I'm heading somewhere cold.

 

I’m using the standard dose of 1oz per 10 gallon. Or at least I think that was “standard”. Been a bit since I studied on it and decided what to do. Maybe a heavier dose would be a noticeable change , I doubt it. But I was really after some lube insurance for my 103,000 mile OEM injectors so feel like this is sufficient.

Yes, I agree. My comments weren’t to take away from your review. Just wanted to share my experience so others can hear both sides of the coin and not expect to see your results.

One of my struggle points was deciding how to mix/store/use the product. I bought the kit with the extra little jugs. Those are kind of a joke. No sight window so you basically would have to guess or just dump the whole thing in. Searched Amazon for see through graduated bottles, eh nothing great. Finally ran across the almost empty Sta-bil bottle in the garage and had a lightbulb moment. It works very well. So well that I would literally buy it just to dump out and use the jug.

Another “pro tip” for those considering a purchase. I ordered the pump kit because who wants to try and dump this cleanly out of a gallon jug? Little did I know it already comes with a valve that screws on the top. I never used the pumps. They would have wasted product and been messier than just using the valves.

Super easy to blend by the graduated marking on the side. And super easy to dispense the proper amount during fueling. Optilube should really consider adding something like this to their lineup for additional purchase.





Yes sir, this is my plan as well. I’ve never actually had any gelling issues. But the truck sits most of the winter so will have summer fuel in it when it gets cold. In the past I’ve used normal Power Service (as a general additive) and plan to just dose it on top of the OptiLube when the freeze sets in. At least until I get some winter fuel into the tank.

 

As the instructions say, one hand pump is about 1 oz. Doesn't get easier than that.
