I have been using Opti-Lube Xpd since I got my truck last year. I usually order the additive in the 1 gallon jugs because of a little discount over the quart size.
This past week I went to the Opti-Lube website to reorder my usual 2 gallons.
PRICE HAS GONE UP BY $10 FOR A GALLON.
That's a 25% price increase folks. ....matter of fact I noticed the 25% PRICE INCREASE ACROSS THE BOARD.
WTF....That's a hell of an increase to slap on customers all at one time.

I am now having second thoughts on using the product...I am considering going back to Power Service Diesel Kleen like I used to run in my other trucks.

I had switched over to Opti-Lube because of this "Spicer Report" that was done about 5 years ago because I wanted the best Lubricancy but after doing more and more research.....there really is no more information.

Diesel Kleen uses "Slick Diesel" in their product now for Lubricancy and I don't think this version of DK was used in the original testing.

This price increase of 25% has left a bad taste in my mouth.

 

is there a real benefit to using an additive in the 2008+ trucks? I bought my truck used with 70k on it, i don't know if it's ever had any additive added to fuel. Assuming it hasn't, is there any benefit to me starting to add some now? I thought the 2008+ vehicles were designed to use Ultra Low sulfur diesel and did not really need any additive to be added?

 

I use Stanadyne, have been for a year now. I used to run Powerservice, never had an issue with either, I only switched because I heard the staandyne dispersed water better!

 

I think that it states in the Owner's Manual that a fuel additive is recommended.
I would have to pull it out to verify that.
I use an additive because it just makes sense to do it. I guess I'm a little old school when it comes to understanding that the injectors and fuel pump needs to get lubrication from some sort of a source. Today's diesel does not provide that.

 

wow! I am on my 2nd gal. and paid about 45-50$ for it.what do you pay for it ? was buying from a speed shop here in L.A. but they closed so was going to buy elsewhere

 

WOW! I just checked myself.
