The old thread on OptiLube vs PS vs other additives sort of died out.

This stemmed from a "study" done on lubricity of various additives to include 2-cycle oil.

Anyone have current views/data on the OptiLube?

Just curious if it is worth the effort to order since PS (which I use now) is so readily and easily available.

if you have access to bio diesel thats probably your best bet!

 

I've been running opti-lube every tank for the last 2k miles and I can't tell the difference from the stanadyne and motorcraft I used before. I say use whatever is easy for you and hope for the best. I run it for peace of mind. Just trying to keep it out of the dealer so I don't have to listen to their lies. 04 6L.

 

The results of the study were pretty straightforward.... run 2% to 5% bio for the best lubrication. If that's not available, Opti-Lube is the next best thing.... and if bio is available, don't use it in the winter if you live up north.

Discussing what you use is pretty much irrelevant unless you can add, "... 7 years and 200,000 miles without an injector problem..." Then, we'll listen. The purpose behind these additives is to replace the fuel lubricity that was lost in the conversion to ULSD.

It will take a long time and lots of miles before the increase in wear rate starts resulting in injector failures or high-pressure fuel pump failures.

 

Thanks for the responses. I indeed want to add Lubricity to the ULSD since my new to me 2007 is the truck I really want to get 200,000+ miles out of.

WWB is spot on. I switched to Opti-lube from Diesel Kleene based on the study results. Unfortunately, bio isn't an option for me as there are no retailers near me so I went with the next best thing. As WWB said, the main benefit/purpose is to provide lubricity. The benefits of which won't be observable until many, many miles down the road. I will say that I didn't see any fall off in mileage when I switched to Opti-Lube from DK (I had realized a consistent 0.8 mpg gain with DK). Seeing that the Opti has about 3 cetane points less than DK at full dosage, I was impressed with the Opti-Lube. But the Opti-Lube is pricey, making it a tough call for many.

 

If anyone is wanting a cheap opti-lube option check out their summer blend for lubricity. I personally bought 1 gallon of each (summer, winter & xpd) to test and for the free shipping but the summer blend is very strong and only requires 2oz. per 30 gal. if I remember right. I haven't used it alone yet but I've tried it mixxed w/ the winter blend 2 oz. summer + 6 oz. winter and see no diff. compared to 8 oz. xpd. I have a case of empty 8 oz. stanadyne bottles so I do my own mix and it have been cost efficient so far. I also have seen no mileage gain or drop from the opti-lube.

 

So how do you find biodiesel ?

 

Look at the pump you get your fuel from, should say right on it if it has Bio content. usually a B number. My BP station in town has B11 (11%) biodiesel mix. It is available at the big rig pumps.

If you have a local FS ( Farm Service) station, they will always have biodiesel... Some times up to B25 !
