Hey All

Has anyone here ever try Opti-Lube XPD?
If so, Did you notice any difference in MPG, Performance, Etc

I have always used Lucas Fuel/Oil Additives, But am interested to see if there are better products on the market today. Mainly looking for an all in one Cetane Booster, Injector Cleaner and Lubricant.

I've used it since I bought my truck last year. Truck gets much better fuel economy than my last truck (Dodge) I started using it because of the increase lubrication of the Opti-Lube XPD, Best mileage I've logged is 24 mpg on a 300 mile cruise keeping the DMAX around 70 mph....Vehicle mostly stock...including the tires....

I've used it since 14k miles...I really have nothing to compare to but I do get an average of 19-21 MPG...This also includes a fuel mileage tune from Rob and synthetics all the way around...My truck also runs pretty quiet...I purchased Opti-lube mainly because of their results when put up against other additives...I did pay 50 bucks a gallon though which does sound somewhat expensive to me.

I use it now.....love it..

I got mine from these guys....only place i could find it.

Great bunch of guys...even called me after I made the order to tell me it shipped.

I got mine from Grace Distributing....some reason the website isn't working......but here is there phone number 405-249-8742.

A normal tank is 4-8 oz per....the summer blend is alot less.

The XDP is somewhat of their all around version....I haven't tried the others yet.

Sounds good. I think that I'll try some myself. I think that it might be a better product than Lucas as far as Fuel treatment. Would be nice to see it on the shelves @ the store to avoid the shipping costs.

BIGON- I went to their website-- Diesel Fuel Improver

Didn't notice any change either way...:D

I recommend 1% SOY BIODIESEL if you can get it. The lubricity is about the same, and it's a fuel, not an additive.

Here's a link to a post on how to mix Dr Don's SnakeOil - a generic additive pack for ULSD. I make nothing from anybody on this - and don't want to argue about anything!:drink

I have a chart that I got from somewhere comparing properties of it to other products... I will have to post it when I get home. I use the XPD also because it averages out to be almost the same price as any other decent additive, and I hope it will help my LB7 injectors last longer.

If ya check the beginning of the thread I quoted above - or better yet the Spicer study that first brought Opti-Lube to prominence...

Lubricity Additive Study Results - Diesel Place

...you'll find that BioD scores BETTER than OptiLube, and it's a fuel, not an additive. If you can't get B01, then OptiLube is the best.

BTW, since B01 is 1 qt per tank, expect it to be a very popular commercial lubricity additive in the near future. It makes a whole lot more sense as an additive than a fuel.

So some local gas stations pumps state it contains 5% Bio diesel. Does that mean the 5% Bio acts as extra lube & does not need lube supplements?

Yep, B05 (5% BioDesel) has the best lubricity numbers going - so the only additives you might need are for gel point (cold weather) and slime prevention (biocide.) B05 also maintains your warranty. (Ha! I see you don't care about that!)


If I could get B05 at the pump I would add .4oz Power Services BIO KLEEN (or .14 oz Kathon FP 1.5) per 22 gallon fillup year round, and add Stanadyne or Power Services white (DFS) as marked on the bottle in the winter months (2x strength if below zero temps are expected.)

Minnesota Biodiesel Mandate;

"The latest mandate calls for biodiesel blends to increase in stages, starting with 5 percent May 1, 2009; 10 percent May 1, 2012; and 20 percent May 1, 2015. The 10 percent and 20 percent blends are mandated for seven months of the year, from April through October, with a fallback to B5 during the winter months."

I'm not worried about lubricity anymore, just if there is any water in the fuel I will have to watch out for mildew causing stuff.

So how do you and the state of MN handle the fact that their mandate violates the warranty on your Duramax?

My manual says 5% max or warranty void.

Not sure, but pre-07 trucks won't void warranty until over B20. I have no clue what they will do with all 07 and newer trucks. The DPF is the big problem.
