ProTectaEngine Treatment 10 Ounce Bottle

This and this http://www.amazon.com/gp/product/B0041OQI7K?redirect=true&ref_=cm_cr_ryp_prd_ttl_sol_1 are hands down, THE BEST engine additives on the market. To be clear, this company has not paid or compensated me in ANY way to write this. Actually i've never even communicated with them, but i assure you, if I do, it will be to to thank them for actually making an engine additive that does everything it says.Give these Testing results a quick look, which put protecta against the majority of used brand engine additives out there.http://www.precisiontandems.com/sfr/protectaenginetesting.htmI've been using SFR Protecta Advanced Formula Engine Treatment for a little over 2 years now, and this Engine Oil Booster(which gets 5 oil changes boosted from 1 of these blue, quart bottles of it. I'm a skeptic by nature, and a cynical, fault finding one at that, but there honestly is not much getting around the facts of these 2 products........THEY DO WHAT THEY SAY, maybe more, but certainly not any less.....Note: I have not tried their other products(ie: the automatic transmission treatment, fuel treatment, or any others)except for the spray lubricant of theirs, and speaking of that.....if you have a brand of spray lubricant that in your opinion is better than average, or just satisfactory for your needs or whatever the case may be, I assure you, this company's brand is AT LEAST twice as effective.... take a look at some of these guys youtube video's for some no BS proof of HOW their products are better.The good thing is they don't have to fill their time slots with pitch's or endearing descriptions, or any other similar crap......they put it to the test and show the details and specs and entire procedure of how it was put to the test....So, I think you get the idea......They are well worth the time and resources one will put fourth in obtaining these products.....And like i said, this is my opinion solely, and is in NO WAY altered, compensated for giving, or even ever communicated with these people AT ALL......No need to, seriously, quality speaks for itself

I put a treatment in my vehicles 2x a year.. Overkill?! Oh ya. But, for the price? Why not. Treatments are late fall oil change and then the spring. MN cold starts are hard on vehicles. This product gives me the piece of mind that there is "some sort of" prtection happening waiting for that cold/frozen oil to circulate.

Not working like I had hoped. I’ll stick with what I know. Lifters louder than ever!!! Went to garage had old additive put in engine now quite right down. Will never use again

My 2013 Subaru has a bit over 50k miles on it. I was hoping this would quiet my valvetrain, more than it has; but it has some! I have used similar products in the past with great success. I will be sticking with this brand, and making follow up purchases with ProTecta for the life of this motor. I may comment more with this at some point.

I've been using this oil additive in my 2004 Hyundai XG350. My car has well over 180,000 trouble free miles thanks to Protecta. My engine is quieter, smoother and cleaner. My car doesn't burn a drop of oil! I'm getting better mileage and my car recently made a trip all the way up to Alaska trouble free. Thanks again, I will always be a customer!

I've been skeptical in the past using many other products who make the claim of engine protection and fuel economy. For me it's been over a thousand mile and I have noticed around 4 miles per gallon better mileage. My engine seems a little quieter. I would recommend this product for exactly what the maker claims.

The engine ran smoothly and torque increased also noticeably . I am happy and satisfied .I will reorder for sure.

This stuff really works I can tell the difference on a cold start up in the morning when it's cold outside. In my opinion, this stuff in better than royal purple.
