Slick 50 Oil Treatment Use It Or Not?

[lineman]

I just bought a 2000 z71 with 75,000 miles on it and the previous owner put slick 50 in every other oil change and changed it every 6,000 mile with 5w30 mobil 1. Should I keep putting the slick 50 in or not? I plan on still using mobil 1 but changing it every 3,000. I have just never been a fan of oil treatments but guess everyone has a opinon.

I've never put oil treatments in anything I've owned , personally I think the are a waste of money! I just traded in a 96 Silverado with 148,000 , got a 02 Nissan Quest with 121,000 and a 96 Honda Civic with 240,000 and none of them use a drop of oil! Conventional oil and Wix filter every 3,000 miles!

Save your money.

did the previous owner do it just because, or was there a reason(i.e. an oil leak somewhere, or for reduce oil consumption)?

 

i had a very minor rear main seal leak in my old dakota, but it was also consuming oil. i think the piston rings were worn out. i used Lucas Oil Stabilizer every 3,000 mile oil change and it significantly reduced the leak and oil consumption.

 

if he was putting it in just because, i wouldn't waste your money on it. there needs to be a reason to put additives. like stopping a leak without paying a bunch for mechanical labor to fix it, if you intend on not keeping the vehicle very long or just can't afford the labor. thats how i rationalized using the additive.

If you read your owner's manual, GM cautions against using oil additives like Slick 50.

Don't be sucked into buying oil additives. Only the people who make them and sell them see any benefits ($).

 

If you use a good oil you don't anything else.

That slick 50 would have done no good, just floated on top of the Mobil-1. Most additives won't mix in with oils now a days.

Just do the Mobil 1 5w30 every 6,000 miles. That's what I do.

elcamino covered it pretty well.

 

Today's oils don't need an additive.

What makes you think this?

 

DEWFPO (doesn't use any additives of any type, just high quality oil and filters).

Slick50????? If you don't know what to do with that $10, I'll give you my address and I promise you, you will get 10% better mileage, your engine will last twice as long and you will have more HP.....

 

I use Mobile1 oil and Mobile1 filter. I change it @ 10K miles. I've had it analyzed twice @ 10K miles and it was just over half life. I've got 84K and don't use any oil between changes.

Lab testing. Lots and lots of lab testing. I'll get that info for you folks to read shortly but in the mean time, read this:

STAY AWAY FROM IT!!!!!! SNAKE OIL!!!!!!!

Let a freind talk me into trying it one time in my 86 S10, ended up tearing engine apart. All rings stuck to pistons. Had to pry off with screwdriver.

 

Engines have had nothing but oil in them since the begining and has worked for years. More so since fuel injection. It elimanated the idiots from flooring a cold engine dealing with automatic chokes.

 

Just my opinion.

[redjewel2ss]

that's why i used Lucas products. all of there stuff is petroleum based and it truely did stop my oil consumption problem. before using it, i was adding a quart of oil every 1000 miles, after using it that was no longer necessary. before using it, my "check gauges" light would come on for low oil pressure; thats when i knew there wasn't enough oil in the engine if i forgot to check the dipstick. after using it, the light never came back on. and i used it for a good 50,000 miles out of the 80,000 i put on the truck the 7 years i owned it, with oil changes every 3,000 miles.

 

but i would never need any of that stuff on my silverado. engines nowadays are much more advanced! my 98 dakota had mid 80s technology under the hood! dodge is always the last one to figure out how to use these technological advances!!!

used it twice and was satisfied/liked it. Can't confirm but heard it gets like jello on the bottom of the pan after a while. Used Duralube and blew two ford motors within 500 miles of introduction. Both motors went the same way. Would not use DURALUBE ever
