I just changed my oil about 2000 miles ago . And wanted something a little heaver with out changing the oil again. Do to the heat. So I just tryed the Lucas pure synthetic oil stabilizer. And add 10 oz to my oil tank . It's a little pricey at $15 a qt.

 

I run i in everything but my blender.. I like Lucas products.

 

I would never use that crap in any vehicle I cared about.

If ya gotta have heavier, add a can of STP (though I don't see the point unless you're running an old shovelhead).

 

I don't think you need to add anything to a good engine oil.

 

+1 on not adding anything .. .

That being said my FIL regularly adds STP to the oil on some of his GM POS cars and he gets 200k+ miles out of them. (We're talking Chevy Celebrities, Oldsmobile 88's, etc.)

 

Thanks to Mr. Lucky! Bob the oil guy has a lot of information at the link he posted above. Very interesting read.

 

I looked at Mr bobs info It did look interesting too. But I'm willing to try things to. So here's what my outcome was . I went for a ride and after the motor warmed up and the stadilizer blended in with the oil. About 5 or so miles I did hear the sound , that sounds like your stirring a empty bowl with a spoon GO away. And I can still hear the tappets making a good sound to. I also check the oil to see if it turned creamy and it was not. So am I happy with the product yes. Do I still want to get 20wt / 60wt yes . Why because I do'nt hear people bragging about it . 2004 sportser 1200C with 22,000 miles on it. Also the ride was about 25 miles.

 

Never have and never will run any additives in any of my junk!
I use the same brand oil I've used for the last Thirty-four years, and will continue to do so.
Use what you want. They'll keep making replacement parts for you guys!
LMAO

I've seen some bad things happen when peeps have done the " additive " thing , maybe things have changed BUT....... good luck

 

Oil additives = Oil Thickening Goo

But if it make ya happy . . .
