Owner reviews for oil additives
My old car was sitting for a year because my sister wanted to drive a bmw. Neglected it. Went to get it back yesterday and oil was under the dipstick, and engine knocked. I added Lucas oil some $18 additive, and filled rest up with oil, was only a half quart under the stick so it took a whole quart. Quieted by half almost immediately, drove 2 hours back home and engine is silent!!
I add 1 bottle of mos2 to my 5.7 hemi in my 2008 ram after every other oil change and just send it until the next change. Extremely noticeable different in engine noise and operation.
Liquid molly & ceratec additive is better than any bs blends a shop will sell you
I use that exact additive in my hemi, and it's noticeably quieter.
I used liquid moly oil additive after I changed my spark plugs and coils and it helped my car from smoking after just one can.
I’ve used this very additive and it made a large difference in how smooth the car ran.
They work and they're worth it if you have a car you plan to keep for a few years to come.
I use the oil additive every oil change + Injector Cleaner regularily.
Major difference - Engine is quieter and much more lively than when I first bought my used car!
I use a lucas every oil change with Mobil 1 5w-30 full synthetic. Would recommend it. 2014 3.0L Q7
I have used that Marvelous Mystery Oil crap twice on 2 different cars - within 10 miles, BOTH blew the headgaskets.
