Anybody running 2 stroke in their diesel?

Does your Mitsubishi L300 make a strange noise? Need wheel alignment specs?

I've used other additives in the past like Power Service but i've been reading quite a bit about the advantages of a dose of 2 stroke in your tank to lube the IP and Injectors, a quitter engine as well as gain slightly better fuel econ. As of this writing i've just filled up at the local Kroger (2.279 a gallon..) and added a quart of 2 stroke (Wally World brand for 12.75 a Gallon) to the tank. We leave tomorrow for the trip to Fla so we'll see what it does. Nothing like testing a theory on a long road trip right? :-)

i add 1/2L of generic 2 stroke oil in mine every fuel tank! Keeps the system well lubricated! I've done that for 2Y now. No problem! You could add additives and such but in the end your are after lubricity! For every oil change, just before when I have less than a fuel tank i put in a bottle of cetane/injection cleaner to flush out till my fuel light comes on.. then refill with 2 stroke oil again! Lubricity is key!

There are a couple threads around indicating some have switched to 2 stroke oil as a "fuel additive". I've heard the ratio 200:1 somewhere. I plan to try it out once I'm through this bottle of stanadyne

Hey! Good to know i'm not alone. I've yet to check the numbers on milage but It's cheaper than Diesel Kleen! We made it down to Fla with no problems! First long drive with the Deli since we got it. :-)

I don't really know anything about fuel or oil but I did find this and were wondering what you guys think about it:

US low-sulfur fuel from the early 2000s did not have lubricity improvers (unlike low-sulfur fuel from the rest of the world), leading to failure of injector pumps and the pervading rumour that "Low-sulfur fuel is incompatible with older injector pumps". (In the early 2000s teh internets were very USA-centric).

Bosch even made a presentation to the California Air Resources Board in 2003 regarding the issue: https://www.arb.ca.gov/fuels/gasoline/m ... 3bosch.pdf

sooooooooooooooo they added them since them and it's not worth adding 2 stroke oil anymore?

Looks like CARB limited sulfur content in 1995, but didn't specify lubricity until 2005. ASTM D975 with its fuel lubricity (and other) standards was created in 2004, but wasn't picked up by the EPA until 2006 . Not sure how the widely CARB standards were followed by the rest of the USA (usually the rest of the country follows California just because it's easier), but it looks like low sulfur diesel fuel without the required lubricity could legally have been around from 1995 until 2006. In the USA.

California (CARB Diesel)
Effective October 1, 1993, the California Air Resources Board (CARB) adopted a diesel fuel specification limiting the sulfur and aromatics in commercially available diesel fuel. Starting in January 2005, California diesel fuel was required to meet a minimum lubricity specification as well. This fuel, commonly referred to as the CARB diesel, is mandatory for use in a variety of applications including both highway and off-road vehicles. The limits and applicability have evolved as follows:
1993.10—Sulfur limited to a maximum of 500 ppm and aromatics to 10% or equivalent. Applicable to on- and off-road vehicles but not stationary engines, locomotives and marine vessels.
2004.12—CARB diesel requirement extended to stationary sources (applies to on- and off-road motor vehicles and nonvehicular sources other than locomotives and marine vessels).
2005.01—CARB diesel required to meet a lubricity requirement of a maximum wear scar diameter of 520 microns by ASTM D6079, the High Frequency Reciprocating Rig (HFRR).
2006.06—Sulfur in CARB diesel limited to 15 ppm.
2007.01—CARB diesel requirement extended to intrastate locomotives and marine engines (within the SCAQMD, CARB diesel must be sold to harborcraft operators beginning 2006.01).

I'd say "correct". As far as I can tell, Injection Pump failure due to low-sulfur diesel's inadequate lubricity was a real thing in the USA from the mid-90's until the mid-2000s, but it's fixed now.

That said, 2-stroke oil won't do any damage (apart from clogging up your injectors if it has too much zinc in it) and people will always *swear* it makes their engines run better. (I swear my van runs better after it's had a good wash and polish, so I'm familiar with the placebo effect.)
