Best One oil additive!
I have watched several reports on this and seems to beat most others in torque checks. I have always used Lucas but am experimenting with this, to see results for myself. I have now used in my Honda motorcycle and my Kia Sorento.......So far so good!Verified purchase: YesCondition: New

Who knows
Who knows if it's any good? The cap was easy to open. The bottle was well constructed, it held liquid. It had a hole to pour out the liquid.Verified purchase: YesCondition: New

Bestline 0il in Nissan VG33
Doing the summer time, protect your engine routine for my aging Nissan VG33E engine and just getting started to tell you the truth. Engine has no history of oil consumption and I'm trying to keep it that way. In order to swap engines with my Z31 '89 300ZX I'm going to need this engine to run another 100K MilesVerified purchase: YesCondition: New

Best 20 dollars I ever spent
Added it to my fully modified 1999 Firehawk and OMG! What a difference! The engine shook like mad at idle before I added it to my oil, left car running while I added it, engine started running really smooth and quiet once done. Took it for test drive and the engine ran without friction for once, and picked up massive horsepower! Rpm's accelerated faster than ever, and powerband became noticeable, like a new cam! Worth every penny! I put it in all my cars now, even radio control cars and my girlfriend's truck.Verified purchase: YesCondition: New

What a fantastic product!
This product really works! I have 285.000 miles on my 5.4 engine and I always have been getting 21 miles to a gallon on open road maintaining a speed of 60 mph. On cruise control. Now by using this product, I have seen an improvement in my mileage at about 1.3 more per gallon so far. Wonderful Product!

works okay
Right off the back with a oil change and bestline you could feel a smooth motor running like day one but after a month or so it feels like its not doing for your car yet its only my first bottle so cant give up on it going to give it a second chance and see if it gives a better resultsVerified purchase: YesCondition: New

It works! Great product.
My silverado had a noise like a lifter problem. I tried many different oil additive products and none of them stopped the noise. After adding BestLine the noise disappeared in just a short time. The noise stayed away for 5000 miles and I just changed the oil and added another container of BestLine. I can't say enough about BestLine. Rate 100 stars!!!!!!Verified purchase: YesCondition: New

Put half a bottle in at the last oil change. 2000 miles later 1.2 miles per gallon better gas mileage. 2012 Nissan Titan SV previous mileage 12.1 per gallon, know 13.3.Verified purchase: YesCondition: New
