Howes or ...?

[Mark Rinker]

What do others here think of this additive? Have run it frequently, but its hard to quantify results.

So far (knock on wood) have ~250K cumulatative miles on two 2006 LBZs owned with no injector replacements - compared to the LB7s owned, am doing better. There is some correlation to when I started using Howes over other brands - but certainly nothing scientific.

Is it the Howes additive, better OEM filtration, improved injector design, or...?

Last week at a rest stop on I 84 in Oregon I talked to a guy that delivers RV trailers. His 2005 D/A, CC, 2x4, DRW has 561,000 miles on it. He uses Shell Rotella 15w-40, and Howes fuel treatment and has never had any problems. He has replaced the water pump, alternator and a front wheel bearing. It sounds like Howes does some good if he could get 561K on the original injectors.

Wow. Did you actually see the odometer? 500K since 2004 would be 100K per year, or 2000/week, 50 weeks per year....

Thats some hardcore driving.

Mark,

The guy opened the door and put the key in to get the exact mileage. I did see the mileage and it was about 80 miles away from turning 561k. The guy said he was a former thirty year 18 wheeler owner operator before he started to deliver RVs. I told him about The Diesel Page and asked him to post his truck and mileage. He indicated that he would but so far I have not seen anything. There clearly are some very high mileage Duramax trucks out there that are running good. If I get 300k out of my LBZ with no major problems I will be satisfied.

WOW.

That guy didn't let any grass grow under that truck!!!
