Engine Additives??

I have a 98 Trep that just reached 100 k's (km). These are basically all city driving clicks. I'm really good with the oil changes and air filter changes, but not anything else. I've never changed any other fluids and the only additive I've used is Fuel Injetor Cleaner.

Does anyone recommend anything? Slick50? Prolong? (waste of money?) etc etc?
My fluids are all in good condition.. except for the coolant .. which I'm planning on changing in the fall...

Thanks for any input!

the only treatments I have ever (or will ever) use is fuel injector cleaner, anythign ele is just a waste of money in my opinion

every "real" test I have ever seen shows they don't really do anything to help your motor or add power

Agreed. I've tried Prolong and Duralube and neither of them did anything except lighten my wallet. Of course this was years ago, before I thought to look on the Internet to see if anyone has ever actually tried these things. Damn informercials made a sucker out of me. :blush:

I saw an engine fail on a 1987 Grand Marquis (suposedly bullet proof engine) because the prior owner used teflon additives that actually clogged up the oil returns.

Good quality fluids and forget about additives

just use some valvoline in the engine...change it every 3-4k...use atf4+ in the tranny and change it every 20k...forget what the book says...if you change the tranny fluid frequenty enough you shouldnt need to do a tranny flush. Oh make sure you change the filer too. Speaking of filters, dont use FRAM filters on the engine the return valve allows dirty oil back into the motor when the engine is turned off.

forget the high mileage oils...they just lighten the pocket...

If we added every fluid and every gimmick device (i.e. Tornado), our engines would be making 1000hp and have 1% friction and drivetain losses. I mean, they all claim a 10-15% improvement, so they should start adding up, right?
Just use fuel injection/system cleaner, I push the Mobil 1 oils, and change everything in a timely matter. Everything should be ok. Mine's got 163,000 miles on mine and runs great, never used any extra additives. And I've always used FRAM oil filters, but probably gonna change next time after reading stuff on here. But FRAM has done just fine for me.
But anyways, regular, timely care should keep the engine running just fine.

Forget the stupid additives. Here's what you are due for to achieve another 100,000 miles:

1. Flush the radiator!
--Old fluid leads to cooling system damage. Replace all related belts and hoses while youre ate it.
2. Timing belt
--You have to.
3. Machine-based engine flush (Envirolution, Bilstein)
--Optional, but effective at removing carbon buildup.
4. Full alignment and new tires
--I assume you have.
5. Change brake fluid
--For maintaining ABS reliability.

Anyone else wanna add to this list?

I not a fan of oil additives that make stupid claim like horsepower increases or better mileage, but.... I use wynns oil treatment, and all they claim is this. As I read a bottle i have
reduce engine wear and friction
neutralize harmful acids
mimiunize rust formation
retard oxidation and oil thickening.

Couldn't really tell ya if it really works, but it sure runs a little, and I say A Little smoother that when I got it.

Also using air manifold cleaner once in a while helps. With both my 95 and 99 Trep the intake tends to get build up once and a while and some cleaner smooths out the idle and increases the milage again.
