Is it gd idea using oil additives that put a coating on engine moving parts?

Question

N/A

Answer 1

I would instead use a high quality 100% synthetic oil like Amsoil. I have the 0W-30 in my cavalier and the 20W-50 racing oil in my well-worn Mustang. http://www.amsoil.com/redirect.cgi?zo=1463115&page=products

Answer 2

I worked in an oil change shop, and it can be good or bad. A teflon coating, such as "Slick 50," used properly will help a vehicle with fuel milage and wear, but many additives change the viscosity of the oil. Using teflon was an obvious help, as I had a customer with a diesel who put about 1000 miles a week on his truck. Changing diesel oil is a very dirty job, and the oil is black when you change it. After the teflon came out, his next oil change wasn't much different than changing a gas engine, the oil was cleaner, and his milage went up by 3mpg. You are not using it on every change, so you are not seeing a change in the oil on a regular basis, only in the engine.

Answer 3

If the engine is low mileage (under 60K), yes it can extend the life of the engine if you follow a regular interval of maintenance.

You'll get an extended life out of the engine, just by following the regular interval, without the additive. So the actual benefit may not be worth the cost, if it needs to be done with every oil change.

Answer 4

If you read your handbook in your glove compartment it will say that the addition of snake oil additives is not needed. Quality motor oil Valvoline, Brad Penn, Havoline, Quaker State, Pennzoil and Kendall will keep the motor clean and running happy along with reasonable oil and filter changes. You can go the extra mile and use a full synthetic. That alone will smoke any shelf full of "dragons breath" wild can claims.

Every NASCAR Craftsman truck,Busch and Nextel Cup motor runs on 100% synthedic low viscosity racing oil. You will not see any advertising for extra oil additives anywhere.

Google: Joe Gibbs Racing Oil and see what their team uses for qualifying, plate racing and full 850 cfm. carbureted motors. All different.

Answer 5

if you do, then go with Prolong. this stuff is amazing. when i was in tech school we had a car we were getting rid of so we put the prolong to the test. we first ran it with the prolong for about 30mins then completely drained all the oil and coolant. we ran the car for 8 hours and it still didn't lock up, so my teacher pinned the throttle down and ran it at full throttle for about 10 mins until the whole exhaust got red hot and my teacher was afraid of something catching fire, so he shut it down. but it never locked up. i have heard bad things though, that after about 20,000 miles, the Teflon starts to fleck off and can hurt things, but i don't know if thats true. we also had another car that we threw a bunch of nuts and bolts down the intake. that car didn't last so long but it did shoot a 3 foot flame out the tailpipe.

Answer 6

i;ve used slick 50 in one engine i had and it felt like i added another cylinder,but all the other engines i tried it on it did nothing i could tell.some people say additives can clog oil passages,but i've never seen any evidence of that in my experiance.try it.

Answer 7

No, don't use them.
