Just wondering if any one has an opinion on an oil additive that is a step above the rest. Just looking for something that will help restore a little compression and reduce friction on a high mileage champion. Thanks
 
Try seafoam, it cleans out the carbon deposits and what not. I heard its REAL good stuff. do a search for seafoam, all i've heard is good things. I'll be using it soon as well.

Theres this stuff called Engine Restore, a buddy of mine used it and said it felt better, but i've never used it personally.
 
i recently used lucas additive, i am not sure what it did but i think it did someone???

Also i have a question to add. Is it a good idea to use additives on a freshly rebuilt motor???

The little display in the store with the wheels sold me :D

Haha. I see that thing everytime. :rlaugh:

I used Engine Restore on my 300 Inline 6 a few years back, and it helped a bunch. Idled smoother, felt stronger.

I will be using seafoam in my engine in a few hundred miles, I'll let you know how that goes.
 
I used that Restore stuff in my old truck a while back and it honestly did help out. As far as the stang goes, I have never added anything to it...but the wheel display...OH it almost gets me every time!!!
 
Don't use any of that stuff unless it's a last resort and you plan to rebuild your engine in the near future. The Lucas stuff is sticky, like the little display shows, but it also allows air bubbles into the oil, reducing it's ability to lubricate. The Restore stuff works pretty well at sealing up leaky valves, rings, etc. The downside is that it really varnishes up everything and that alone can cause problems. I don't see anything wrong with running Sea Foam through every now and then. It just cleans things up. I'm not a believer in it, though.
 
I recently read a very informative article on additives and oil..they tried several of the current market brands. The results were a little bothersome, especially when the additives actually caused a foaming action with the oil...not a good thing in my opinion. As for additives in new engines...NOT A CHANCE in one of my motors...but hey it's yours not mine.

That is a great site!
Thanks for posting it!

As far as adding additives to fresh motors, I would think this would be similar to running synthetic before complete break in. Most ring manufacturers (at least the ones I considered buying from) warned of switching to syn before breakin. The explanation tends to be that the better lubricant will prevent the rings from ever seating.

IF you use a good engine oil, I can't see how an additive should ever be necessary. But I would like to hear learn more about this.

Yep. it is glazing. One can run synthetic from day one on a rebuild, but accomodations need to be made with the machinist to allow this.

I also am not a fan of oil additives. And I would steer clear of anything with teflon in it.

Good luck.

.

Out of curiousity, I don't suppose you know what those accomodations might be? I am guessing it has to do with the cyl bore finish?

You gotta admit though, that Lucas oil display thing is cool :D

No matter how many times I have seen it I still spin the wheel everytime :p

Yeah, no matter how many times I drive past a wreck on the highway, I still take a look. But that doesn't mean I want to be in one:jester:

:stupid: i'm more prone to agree with this one, don't get me wrong i've used the restore in my engine because it just wasn't feeling as peppy as it used to and it did help, but i consider those additives to be a band-aid fix for a problem that requires much more attention...i know my tired little 306 is in need of a trip out to the pasture. it's getting ready to be yanked out anyway, and have a new powerplant grace the space between my fenderwells.

oh-and whatever you do-don't use that engine flush stuff-it's like putting solvent into your oil, a great way to break down that tiny film of oil (usually around 0.0015"-0.004") that all of your friction surfaces ride on...good way to fry your bearing and journal surfaces.

You got it. I would not have a motor built this way (it is similar to the same provisions cars with synthetic factory fills have done), but a little time is spent on the wall and rings prep.
