If you're like me, I've tried all the so-called "boosters" and "cleaners" recommended out there - and NEVER had any of them seem to do much of anything. Like, Ho-hum. I put this into my little 2006 Toyota Tacoma yesterday before running an errand - and BOOM! (in a good way), my truck seemed to have a super-charged new engine! I have to relearn how firm to press the accelerator again - because now I just seem to touch it and I feel like I could do burn outs! No lie, this is the best. I've used several products by MotorKote, and every single one has been outstanding! I'll never buy anything from any other company ever. When you find excellent products from an excellent company - that's the hardest part. Everything until now has been hype. MotorKote is the best - and I thank you for all your hard work and great products!

More bang for your buck

MK Hyper Octane Boost seems to be a high-quality product. The octane rating at the pump is only an average, so I think the MK additive helps provide consistent performance even when the fuel quality varies. And, it says "Made in the U.S.A." right on the bottle.
