Dura Lube Engine Treatment | 32 oz., 6-Pack

been using this product for 20 years now.... use it, car runs so nice and quiet. Every oil change, my Subaru has over 200,000 miles...the last one I sold my Legacy with 645,000 miles and still got $3500. for it. My engines are always in great shape and I know it is the Dura Lube...seriously

I have used this product since the mid 1980's I performed a little test with a friend of mine. We used small piece of steel mand a sedaline torch. We clamped the steel level and took the torch from underneath we heated the medal until we had a red glo in the center about the size of a quarter the steel was probably 4 by 8 in. We than had 3 other very popular oils or additives at this point we then poured a little oil tsp. worth directly onto the medal about half inch from glo we did this with the other 3 major brands we had on hand. All 3 did the exact same thing They ran from the heat. I mean this oil went to the farthest point away from the glo spot and ran off the edge and these are 3 of the most popular brands available. We the. Took the Duralube and did the same test. Wow was I amazed at what we were seeing the Duralube immediately ran to the glo. Yes you heard me the Duralube attacked the glo it went to the heat. Now let me ask you what do you think happens to your engine parts when the motor is runnind. They get very warm. I was sold instantly. I have used this product since and every product that they make my cars run further, farther and smoother then I could even imagine . This Product Does What It Says!

I have used dura lube for miny years never had a problem it does what the bottle says it does the motor is super quiet works well in fully synthetic motor oil 🛢️

Great additive/lubricant for your car. I've been using this for about 2 yrs now and I've definitely seen an increase in miles/gal, but most of all the car starts w/barely a 1/2 turn of the crankshaft. If I'm a 1/2 quart or so low I only add Dura Lube not my usual oil - Mobil 1.

Item arrived leaking at the seal.

Good synthetic. Remember to shake bottles well for two minutes.

I’ve been using this product every hundred thousand I put it in my car right now. I have 360,000 miles in Harley Byrnes any oil.

This is Superb oil treatment.... i’ve been using this for over 15 years. I had a 1998 F150 four-wheel-drive and got 320,000 miles on the engine before somebody T-bone me and wrecked it. I hardly did anything ever for maintenance to the engine. I used Duralube all the time & the results were amazing my engine was quieter & my gas mileage increased. I believe your engine will last longer. There’s just no doubt about the lubrication of the product. So now I use it in my newer BMW SUV and I’m getting the same results quieter more efficient running I champion this product unbelievable on the market.

Very helpful

Duralube has been around for atleast 30 years. Ive used it before and Im guessing it does what it says it does. Never had any engine trouble.

Excellent lubes. Cools the car, makes it silent and increases mileage of the car.
