Recommended Posts

hey guys i have a quastion, my sister visted last week end and mentuned she uses lucas oil additive in her car "01 grand prix". says her father has used it sense he bought his truck and it has over 300k miles on the motor. wether thats true or not i dont know.Any way i thought i remember reading an artical on oil additives that said not to use them. but im not sure if its just my gold fish lv memmory playing tricks on me lol.

Whats every ones stand on oil additives like lucas ect. iirc the artical i read was for slick 50 or something like that. it talked about the additive causeing tiny air bubbles to form in the oil giveing it a milky color and that was a bad thing. but again im not sure. What do u guys think, are additivs a good thing,shoud i be useing it? Just for the record i have a 00 deville dhs with 66k miles. I use castrol 5w30 dino oil. And i change my oil about every 3 to 6k miles.as close to 3k as i can.

I actually have a gold fish that has a great memory, no kidding...

Anyway, we do not believe in any type of additive at all, no Lucas, no Seafoam, no STP, no injector cleaner, nothing

You could use Chevron Techron in your fuel tank to clean out the injectors and combustion chambers, but use it according to the directions. If you wanted to add something you can get some GM EOS which and add a quarter of a quart at each oil change, it adds ZDDP or zinc that has been reduced by federal gov apparently for environmental reasons

Here is a link to an explanation of ZDDP

Slick 50 worked for a couple of years in the early 1980's but you didn't need to renew it. They went through some corporate and management stuff and decided to pitch the Bishop formula and go to emulsified Teflon which not only doesn't work, the Teflon people say not to use it in engine oil. At that point the Slick 50 people changed their name from whatever it was and said to renew it every 50,000 miles, thus the 50 in the name. It doesn't work. It's a fraud. It went through several ownership changes; now I think it's owned by Penzoil (someone correct me if that's not right) who does not promote it.

Oil additives are for people who don't maintain thier oil correctly, additives cleans sludge, but then again so does kerosene. If you maintain your oil correctly you should get no build up of anything. As for the slick 50, I had a friend who had a main bearing going and added Slick 50, the motor held out for a few months. When it was time to rebuild the motor, the mechanic could not get the cylinders honed because the stones couldn't get a grab on the cylinder walls so it had to be rebored. I would have to say Slick 50 did coat the engine parts with a good slippery protectant.

Wildcard...My 1994 STS has been in the Family since it was 5 years old,in that time the oil has been changed every 5K kms or according to the OLM. I've installed STP,Lucas oil stabilizer,GM EOS over the years and 185,000 miles later it's still runnig strong..pick what you want and run with it :D

Hey lets not forget MMO (Magic Mystery Oil) and tranny fluid..... We actually had a member use Seafoam and shortly thereafter he needed to replace his engine due to knocking and oil burning.

The point is additives are NOT necessary or recommended unless you like a lighter wallet. And that came from Al Cline who was on the Northstar Powertrain design team, not me

I am a big fan of GM EOS and changing the oil on time

Here is a link to an explanation of ZDDP

i do use techron every 6 or so tank fill ups. i use seafoam in my montecarlo "now my mothers" but with my motor being so old "11 years" i figured despite the low miles the seals ect were prob a bit worn and i did not want to use the sea foam as i hear is stronger.

i checked on that zzdp stuff, according to that site it says zzdp is only important to older cars pre 94 iirc. so i dont know if it would help with my motor?

I would not run anything other than normal maintnence.

I run chevron techron once every 6 months just because I dont like the gasoline quality.

But a well maintain shouldnt need any addatives. If it isnt in the owners manual it shouldnt need it.

It is usually a mental feel good

GM FAN FOREVER

Nice, clean, luxury= fine automobile

Forget any kind of oil additives. Change the oil and filter when the oil life monitor is close to 0% with the conventional "dino" grade of oil your owner's manual specifies. 3000 mile oil changes in a 2000+ Northstar are far too frequent.

With regard to adding ZDDP, as you noted, 99 and older engines use rubbing element wearing lifters that have increased friction when compared to the roller cams from 2000 on. the 1/4 quart of ZDDP additive is imperative on a 99 and older Northstar if you ask me. Given that ZDDP has been reduced in oil, I personally would add a 1/4 of a quart, but you are correct, from 2000 on it is not as critical.

I realize the info posted was for a Northstar but for the benefit of others: The LT-1 engine used in the '94-'96 Fleetwood Broughams, Buick Roadmasters, Chevrolet Caprice/Impalas had roller cam followers.

That is good to know kevin, I did not know that.

Oil additives = snake oil. Their manufacturers are followers of the Church of P.T. Barnum.

Blue Corral, the manufacturers of the Slick 50 paid one of the largest (if not THE largest) fines ($20M) by the FTC in U.S. history for false advertizing.
