If you want your car to drive and it's engine to run smoothly, I highly recommend Slick 50. You will appreciate its contribution to power and silky drive. I'm speaking from experience. My only advice is make sure you purchase one appropriate to your to the size of your engine.

Excellent product

Used this for years on and off in various cars. Never sure if it does great thinga or if it's 'snake oil' ......but used it many years ago in classic 1988 BMW E30 which lost about 3 litres of oil on a journey. (Long story) ... Convinced myself that the slick50 saved the day. No damage caused to the engine

Used Slick 50 for years very pleased with it. Good price, it arrived on time and it's good for my car.

Good product

I've always used oil additive s just to make sure everything runs smoothly as it should changeing oil more frequently also keeps engine's in top condition also but in my classic car's I give them a little extra eg slick 50

I have been using this for year. A true friend to your engine ❤️

Dunque, devo dire che lo uso da più di quindici anni...e con tutte le auto che ho avuto, ho sempre superato tranquilla i 350.000 Km. Senza aver mai riscontrato nessun problema al cuore del motore....anzi, l'ho ha sempre mantenuto giovane fino all'ultimo momento in cui ho deciso di cambiare auto. IL prodotto è meraviglioso, fin da subito si riscontra un aumento di Potenza di circa 4/5 cavalli (su motore 2000 Turbo Diesel provati al banco a rulli) ma quello che piu stupisce e un aumento di coppia ai bassi regimi...ad es. se su un tornante in salita magari devi scalare in seconda per far riprendere il motore, con questo prodotto nel motore, adesso sicuramente ci vai in 3 marcia. Posso anche dire che ho riscontrato un minore consumo di carburante, in città da 11 km litro ai 12 km litro, In autostrada dai 15 km litro a circa 16,5 km. litro. Pero secondo me dopo dopo qualche migliaio di km 7/8 mila km l'effetto incomincia a svanire, magari e una impressione, ma quando rifaccio il cambio dell'olio a circa 2000 km e rimetto lo slik 50 nel motore ,sembra rinato...comunque ottimo prodotto, lo consiglio per tutti i tubi di motore.

Spürbar besserer Motorlauf nach einigen tausend Kilometern Laufleistung. Weniger metallische Geräusche durch Oberflächenglättung.

Hace años que lo conozco y utilizo va muy bien, reduce el consumo y la rumorosidad del motor.

All these years I've been adding Slick 50 to every oil change and one single time I stupidly neglected picking up a bottle for my 6cyl GMC pickup (286,000 miles ) and in the process of towing a trailer packed with furniture and odds and ends on my way back to my home (2 hours away) my pickup very suddenly overheated and warped the engine head. That was my $4,000 lesson. I'll bet I NEVER have another oil change without SLICK 50. Slick 50 is the best engine insurance policy you can possibly buy and it's VERY VERY AFFORDABLE. WE

I knew an old man in Southerland Oregon sometime in the early 1980's who introduced me to Slick 50. He was an automotive master. He had retired with 30 years from General Motors. The man had built a total car from scratch of his design. Impressive guy, to say the least. He put the stuff in all his motors, tractors, autos, motor cycles and lawn motors. He claimed it was magical. And I asked him order me a quart which was $55.00 at the time and it took 3 weeks to receive as it was not yet available in the USA. About a year later I saw it advertised at a hardware store in Reno Nevada and they had a small Wisconsin Motor outside the store running with no oil in it at all. It had been running all day. And they did that every day. It had been treated with Slick 50 and nothing else. I can only say I've been using it for a long time now and have yet to see any signs of failure. I had an 84 Toyota pick up that I sold for 2 grand in 2005 that had 385,000 miles that I took in to the mechanic for a pre-sale check up. He said the motor checked out perfect on all tests. He said he'd drive it anywhere. I treated it with Slick 50 every 50,000 miles. I see lots of critical statements made by rich companies who would be happy if Slick 50 weren't around. You know what? It's a big planet, there's room for them too. But heck with them and their BS. I love the stuff, that's my opinion.........SkipBale
