370Z car
Hi there! I just changed a clutch and changed manual-trans fluid to include engine oil. Previously however I had forgotten to add the trans lube package from your website when I changed oil I added Both: I added one to the engine oil and also added the one I had forgotten to the manual transmission. and wow! it made a huge difference to the manual transmission. It is really much smoother and much less "notchy" when shifting between gears. Not to mention the engine revs much better. The engine in this car is made for the diamond nano-tech by the manufacturer as it's in the Nissan oil, however I don't use because I can get additional benefit with this product. Good stuff -Thanks!

Service is top notch. I
Service is top notch. I have called for recommendations, and I have had Perry actually answer! Not only did he answer, he knew who I was. I have been ordering these products for years. Years. And he noticed. That’s service. Very rare these days. It works. Not just the products. The service. Awesome.

Amazing stuff!
I have several cars of all types, and I will not use anything but these products in them. The car doesn’t feel right unless it’s had these lubricants, and it shows—one is an Escalade this is almost 150K miles. I bought the used car kit when I got it aboit 30K miles ago, and it instantly ran better. Never disappointed 😊

When only the best will do.
I’ve tried so many different brands without seeing or hearing any real difference. But this is the real deal. Made my engine smoother and quieter. Have a customer for life. Already got a couple friends using it as well.

From the beginning I have had great faith in BestLine as the best engine additive. I have tried many additives before and and Bestline is appropriately named.
