I have a 2003 GMC 2500 duramax & i have heard that with the low sulfer fuel I shoud be adding a fuel additive to each tank for better lub for the motor. Any suggests or comments would be appreciated.

Works fine for me. http://www.powerservice.com/dfs/ kipsterk 02-19-2008, 04:53 PM x2 I've had good results with it so far. 14wntr 02-19-2008, 05:46 PM x3 ps is the way to go tator1 02-19-2008, 05:50 PM X4 PS is the way to go for sure.

A B2 is plenty to do the job. There is a study posted on the forum. Stanadyne is the only additive GM recomends.

Buy it in the gallon jugs with a couple of single shot bottles that you keep refilling so you don't waste time at the pumps. Helps with anti-gelling also. ebolavirs 02-20-2008, 02:28 AM If you read the additive study the top performers are listed. None of them have been mentioned in this thread thus far outside of biodiesel. Read the study, see what is easily available to you and make your decision. That way you will have more of a scientific result instead of "what i think is good". rockinW 02-20-2008, 11:19 AM x10 on the optilube xpd .....I like it RI Chevy Silveradoman 02-20-2008, 09:43 PM Stanadyne! thejdman04 02-20-2008, 10:28 PM ps or howes adamrc 02-21-2008, 01:23 PM As srjacob mentioned, the best for lubrication is biodiesel. A small amount makes a huge difference. VB Dually 02-21-2008, 02:56 PM If you read the additive study the top performers are listed.

The results are interesting/surprising. firepoggy 02-22-2008, 04:01 PM Stanadyne here, made the mistake of buying GM's additive once. ZL-1 02-23-2008, 04:04 PM Stanadyne Performance for me.

MEANMAX 02-23-2008, 04:46 PM Optilube XPD,By far the best I've used and I've used them all. NoWake200 02-24-2008, 01:16 PM Stanadyne here, made the mistake of buying GM's additive once. Why is that.... I am just wondering what you noticed. I just ordered Opti-Lube. Chromer 02-24-2008, 01:29 PM Here's that lubricity study everyone has referred to. If you have any questions about fuel additives, especially lubricity, this is a MUST READ! http://www.dieselplace.com/forum/showthread.php?t=178848 crusherguy 02-24-2008, 02:40 PM Stanadyne or DSG 4+Premium. Be very careful of Howes, tests always rate it poor for lubricity. | ||
