Instant results for camry 2008, 175 thousand miles
Erin Terrell✓ Verified Purchase•February 1, 2018
Poured in, started the engine, and had some work, so I didn't start my drive until 39 minutes, when I started driving, I noticed the product already started it's spell. Right now I'm driving. Steering is so smooth now, so are brakes, and I can see the engine running smoothly.its accelerating smooth. Check engine light is gone for now. Waiting for engine noise reduction. Will update review in 24 hours. Lovely product.
Worth it
Corey D.✓ Verified Purchase•January 31, 2018
Seems to clean and work well compared to the Lucas and other products I've used in the past. It is worth the extra few bucks. I mixed with 20 gallons of fuel in my F150 and saw better throttle response and idle shortly after.
Cured my baldness
XNOR✓ Verified Purchase•January 19, 2018
This is the best out there - it is good for baldness, impotence, "performance problems", brain fog and also to keep all evil spirits away - you get it right - it is the ultimate Snake Oil, from the most exotic Snakes found in the deep jungles of India which are only to be found by a select few natives, it is a closely guarded secret only the great Maharajas knew about and now Red Line has brought it to America.
Jokes apart - this is pretty good, used it on my 2003 Nissan Altima - improved the engine sound, there was a sort of sluggishness on acceleration which seems to have decreased.
It is better than SeaFoam or Marvel from what I have seen.

Saved me a gasket replacement
mountaineer✓ Verified Purchase•January 18, 2018
Been using this product for about 7 years now. Was getting an engine code in a 2002 Chevy, too lean bank 1 and 2. They wanted to replace the head gasket so I figured I would try a liquid product. Sea foam didn't help. This stuff, in just one bottle, cleared the code and completely smoothed out a rough idle when cold situation. Many years later don't get that issue and haven't had any fuel related issues. I use it about every 5k miles.
wouldn't trust any other name in automotive additives or high performance products than Redline!!!
synthetic✓ Verified Purchase•January 11, 2018
Works like a charm, wouldn't trust any other name in automotive additives or high performance products than Redline!!! I race cars and the only products I will put in my expensive equipment is Redline, you can't beat the performance wrapped around that logo.
