Speedol F6 BOR Strong Nano-Technology Motor Oil Treatment | 11.2 oz. (330 Ml) | High Performance Gasoline and Diesel Engine Oil Additive

I have a 1993 Toyota Tercel with 260000 miles on it and after an oil change and adding this product I've noticed that she runs smoother. I do my oil changes at regular 3500 mile intervals, with conventional 10-30w. Only time will tell if the product continues to perform as this is day four of daily driving to work and back 40 miles to and from. One thing that id like to mention is they recently changed the price from 15$ to the 20$ it is now.

Surprised it was a watery liquid.But it quieted the 4 banger 2.5LTEngine winter Valve clicks on start.

Quiets noisy lifters, engine seems to be running smoother too! Going to use it in ALL my cars.

It's a good friction modifier for engines but a little expensive considering there are comparible products for less.All together a good product though,works well.

"I've been experiencing a slow start with my car for the last few winters. This bottle greatly reduced the cold start. Motor also now runs a bit smoother. Thank You Speedol!”

love this product cause it works.... best nano treatment Ive ever used....🌟🌟🌟🌟🌟

Added to oil in an 07 HHR with 2.4l. 160k. Idled smoother with no issue for 3500 miles

I used this on my truck. I like the idea for long life on my engine.
