It' definitly not easy to know which regimen to follow or service to perform to keep your engine and it's components in tip top shape. I've seen countless cases performed by others and even myself early in life that have had adverse affects with performance and longevity. So many additives on the market now it's ridiculous. There's a market for it, - it BIG because so many fall for the hype...misleading hype! Allot of the stuff may have worked somewhat for the older generation push-rod engines, but do nothing for theses engines...more harm then good. Merchants can still push these products because it's not illegal to 'sort of mislead' the consumer. That's where these forums come into play. Many of us have learned thru interest and experiance to actually get to the bottom of things.

This is going long, so I probably won't tell a story here, but with these engines, - I suggest ONLY using the procedures I suggested in my last post in this thread. I'll add to that a bit, -

1. Only use the injector cleaner I mentioned above, - only in moderation. Not that much at all if any. Probably the worst thing injector cleaner does to the engine is ruin the spark plugs. If you go the least little bit overboard, the plugs will cake, bridge and loose most of their performance. The newer the plugs, the faster this happenes. So when it does, many are left with scratching their head.

2. NEVER use Seafoam in the tank or thru the vac line. It does nothing in the tank. Suck it thru the vac line and you either do minimal, medium or heavy damage for sure. Minmal-heavy to the O2's and converters. White smoke = product. That's all that's burning. Light brown to dark smoke and your melting, burning, deforming and plugging up your convertors. This is the worst product to use in an engine. It either does absolutely nothing or causes damage...so much so that it could cost you an engine with the first use.

There's no need for additives - for the most part, - just regular maintenance. Like I mentioned before, there's a few dealership services that actually work that safely burns off residue and foreign matter or removes thru a stand alone filterers system. Such as the BG Service and MotorVAC Service (a favorite). The Motorvac isolates and removes everything it breaks loose seperatly. Great service for HM engines. I use to get that done every 3 years, but I haven't put may miles ion the truck latley...so it's been awhile.

If you want some healthy longevity with these modulars, that's the best way IMO.
