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

This has saved many of my cars engines from overheat, and extended the life - great Stuff

Great engine treatment keeps your vehicle running smoothly.

I have used Dura Lube for years and I always add a quart each oil change in all my vehicles including my diesel trucks.

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!

Dump in a quart to your crankcase when changing oil first, before adding the new oil. This revived my oil-burning 2009 Camry 2.4 now at 493k miles (I shall post a photo of the odometer at some point). It has no solid particles, so it's ideal for freeing stuck piston rings. I also noticed a 2-3 degree decrease in running engine temperature, from 186 to 183 F. It quiets the engine and seems to optimize as well as work in harmony with both conventional and synthetic oils I've used. If you are like me and prefer to keep high-mileage engine alive and well, use this. You cannot go wrong. You are absolutely getting your money's worth.

I use this stuff at every oil change in my 2015 Prius V and it’s smooth sailing 🏁

I have use this product since 1998 and it does reduce engine wear. Get 1 MPG more One car drove 250,000 pluse and not overhaul required

I have been doing car repair for over 50 yrs...yeah...that's depressing, right? Anyway, I have tried many of the additives that promised the moon but truthfully didn't deliver any significant difference. DuraLube actually does work. I first used it on an older Toyota pickup (stripped down version with no tachometer). I drove the truck for over 100k miles and I knew how it sounded, where to shift by the engine sound and feel. I added Duralube and noticed I was 3-5 mph higher in each gear. Acceleration was smoother and faster. Engine noise was decreased. Tried the teflon-based products with NO difference and went back to DuraLube and duplicated my results. Impressive. Its the only additive I recommend to friends and neighbors. I use 1/2 qt on each oil change to keep up the protection. Excellent product.

Very helpful

A friend of mine calls this "royal jelly". I've been using this for about 5 years, adding a bottle every oil change. With high mileage on my car, my engine is noticeably smoother, quieter and zippier.

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.
