Lucas Oil 10130 Pure Synthetic Oil Stabilizer - 1 Quart

Top tier product always, make sure product is warm, not freezing temperatures as it will pour very slow

Been using this for a few years now. Seems to help with keeping the viscosity of the oil in the preset range. Have not had any engine issues.

Always good and good price

I love using Lucas pure synthetic in my vehicles. It was recommended to me by my mechanic a few years back and I have used it ever since. My vehicles run smooth and I've noticed better gas mileage. I use 20% of the oil capacity and never had issues.

I use Lucas for all of my 4-stroke engines. Increases fuel mileage, and gain some quietness. Keep that engine clean and free of leaks. End seal smoke. Just put it in there

Great product. Worked great for helping to quiet down noisy lifters I had on my ram 1500. Will be adding at my oil change intervals

Background: I've been using the "Lucas Heavy Duty Oil Stabilizer" for a few years in my old, high mileage SUV which was used only occasionally for towing a boat and for winter storm driving. It would often sit unused for a month at a time. When started after a long period of no use, the engine would make a horrible, dry, grating, mechanical noise which I knew couldn't be a good thing. So, based solely on manufacturer claims, I started using the heavy duty stabilizer. Much to my pleasant surprise, the nasty gear/bearing noises totally disappeared immediately after my first use of the product and have never returned. Currently: I recently traded in the old SUV on a low mileage, gently used one of a different make. When reading up on my new SUV online, I found out that this particular motor has somewhat of a reputation for a rattling, dry mechanical noise upon cold startup which would last until the engine was warm. It was a sound I heard immediately after the first cold start at home. It wasn't nearly as bad as the sound from the old SUV, but it bothered me none the less. I immediately thought of using the heavy duty oil stabilizer, however, my newer car requires much thinner 5-20W oil, and synthetic oil is highly recommended by the manufacturer. So I bought the "Synthetic Oil Stabilizer" and did a complete oil/filter change and added one quart of the stabilizer. The next day, the engine fired up and didn't even show a hint of the noise I had heard previously. Still no noise 2000 miles later, even after a couple weeks of non-use at a time. When I used the "synthetic oil stabilizer", I noticed it looks and feels totally different than the "heavy duty" stuff. It's thinner, pours easier, and has a clearer, somewhat milky look to it. But does it do EVERYTHING they claim it does? Who knows. But I do know that it eliminated my dry starts in the newer vehicle. I've been tracking gas mileage and haven't really noticed much, if any, difference. But I wouldn't expect much improvement on a type of car that doesn't get great mileage to begin with. Why only 4 stars? The only way to know if the stuff does EVERYTHING they claim, would be to track mileage over a long period of time, do a complete engine tear down, run dyno tests, and compare results with an identical vehicle which didn't get the same oil treatment. Unfortunately, there doesn't seem to be any such tests/comparisons. I think Lucas could do a much better job of proving their claims than they've done up to this point. Until I see some kind of proof with a scientific comparison, or when I tear down my engine at 250,000 miles (which isn't going to happen), 4 stars is the best I can do. However, as I stated, I know it works to eliminate my dry starts. That's worth 4 stars for me. I hope some of this is helpful to you.

Major problem was resolved with integrity by Lucas. I ordered (4) one gallon jugs of Lucas oil and received a box labeled 32 pounds, but contained 1 gallon jug of oil (8 lbs). I notified the seller of the problem and they resolved the issue, exceeding my expectations. Using Lucas Oil Motor Additive to replace 10-20% of the oil I use in my diesel vehicles is less expensive than using 100% Synthetic motor oil BECAUSE: I use 2 quarts of Lucas to replace 2 quarts of the 12 qts the truck requires (about equal in cost), and I can extend the truck oil change by 10-20%.

Pour mon Harley en ajout avec mon huile. Le top

Als Besitzer eines VW TDI EA288 Motors, habe ich - wie viele andere auch - das Problem, dass die kombinierte Öl/Vakuumpumpe im Kaltstart Geräusche macht, welche sich nach Lagerschaden anhören. Der Oil Stabilizer (ca 300ml) im Mannol 5w30, reduziert dieses Geräusch auf ein Minimum. Es ist nachwievor hörbar, aber bei weitem nicht mehr so heftig! Somit hat der Zusatz einen positiven Effekt - er erhöht die Viskosität, ohne dass man bei den Additiven Abstriche hinnehmen muss. Klar wird damit das Öl etwas „gestreckt“ jedoch ist das kein Problem, sofern das Öl bei maximal 15.000km gewechselt wird! Eine Flasche reicht bei mir somit für ca 3 Ölwechwechsel, bzw 3 Jahre, was den Preis in Kombination mit dem günstigen Mannol wieder relativiert. Volle Empfehlung für alle VW/Skoda TDI Fahrer ***** #### Tipp zum Einfüllen: Ich habe die Flasche LucasOil zunächst in warmen Wasser erwärmt und dann in einem 1L Messbecher 300ml Lucasoil mit 300ml Mannol-Öl vermischt. Das Lucas Zeug pur ist nämlich wie Honig und könnte - wenn es direkt und unverdünnt in die Pumpe gelangt - evtl nicht angesogen werden. Also: 2l Öl in den Motor einfüllen, dann 0,6L Lucas/Öl Mischung, Rest mit Öl auffüllen bis die vorgeschriebene Gesamtmenge (bei mir: 4.7L) ereicht ist. Am besten danach einmal ein Stück fahren um alles sauber zu verteilen.

Great stuff, heckuva deal

I like this oil, I don’t know why but I trust it, feels like the engine goes quiter, healthier off that makes sense.
