BG RF7 #107 Engine Oil Treatment - 11oz can

I have an old 95 chevy truck 350ci with 350,000 miles on the engine. I've used a high zinc oil since it was new. Around 300,000 miles #3-cylinder spark plug would oil Foul. About every three months I have to take it out and clean or replace it. It would get so bad it was like you pulled the plug wire and were running on 7 cylinders. Started using RF7 and about the 3rd oil change that problem was about 95% fixed. I just changed my plugs after 30,000 miles. Very little oil fouling on #3. Not enough to make it run bad. I always thought engine treatments were a marketing gimmick like Slick 50, but this one worked for me.

After doing some research online I came across this product, I was experiencing low oil pressure light in my car and it was driving me crazy, so I decided to give it a try. It’s been almost 6 months since I started to use this product and so far so good, I haven’t seen that low oil pressure since then. (Knock on wood). My car is an 2001 Audi A4 with 280,000 miles. After switching to Liqui Moly motor oil and adding two cans of this amazing BG motor oil additive my cars has been driving just fine and I will continue to use BG products until I own my car. I hope my review help other people to get to try this additive. I strongly recommend it!!

I can not believe how great this product works. I was on a road trip in my 2000 Ford Expedition with 180,000 miles. The Ford suddenly started smoking and excessively burning oil. I did not have an oil issue previously had never had to add oil between changes. It started burning a quart every 400 miles. As U was away from home I stopped at mechanic shop. He recommended BG RF7 and added a can to the crankcase and topped it off with oil. It immediately stopped the smoking, but the oil consumption continued at the same pace for about 1000 more miles. Then, all of a sudden the excessive oil consumption stooped. I am now back to the original oil usage of about 1/3 quart per 1000 miles. I don't know what was wrong with engine, seals or whatever, but this product cured the issue. I will report back to product review again if circumstances change

I gotta tell ya. I have 2005 Cadillac SRX with the 3.6. These are notorious oil burners and mine was burning about a quart a month with only averaging 10,000 Miles a year driving. Motor has 150,000 miles on it now and has been burning up oil since about 100,000 miles. Consistent oil changes with Mobil One synthetic. Tried Slick 50, Marvel oil treatment and a few others. No difference. Tried this on a whim. Put it in with the oil change in September 2020. It is now January 26th 2021 and I’ve added 1/4 quart since then. I don’t know if this stuff is coating the piston rings or the valve seals or what it’s doing but bottom line....this stuff works for high mileage oil burning engines.

This product is just as advertised and works exceptionally. My car was having issues with smoke coming out of the exhaust and after using two cans within 2-3 months it has decreases the exhaust emissions by at least 80 percent. I’ve tried other oil treatments and this by far has to be the best I’ve tried and worth the extra cost.

Works as advertised. Have a 25yr old Kohler air compressor with worn rings and not in the market to buy a new one and don't have time to rebuild. Previously it smoked even when warmed up, after added half of this can, it smokes a little when cold, but smokes very little when warmed up and it runs a lot smoother. It will give me some more time before rebuild is needed.

Used it in my old pickup that had noisy valves and lifters. This stuff really works !

I got my oil changed and put it in my vehicle has 106,000 miles. I went over 100 miles and the motor didn't use any oil. I guess it will b a matter of time to c if this product will work. FINGERS CROSSED.
