Lubegard 30902 Bio/Tech Engine Oil Protectant, 10 oz.

Cured my RAM Hemi-tick before it got too bad. No more engine noise. Perfect addition to the Mobil 1 oil that I use. Great product.

my transmission mechanic recommended lubegard trans products when i was experiencing trans slips in my civic at 130k miles. my car now has 252k miles and lubegard dramatically improved my situation where i now don't experience any more trans slips. since i was so thrilled and impressed with their trans products, i decided to try their oil additive. i used to be a lucas guy, which seemed to be fine but i think this works even better. my car runs SO SMOOTH after an oil change. i contacted the company about how much should be added and they said 3 ounces per quart. my civic takes 4 quarts, so i have my mechanic add 12 ounces of lubegard. i do a ton of stop and go driving doing deliveries and like i said, my car has 252k miles and still runs really well. i truly feel lubegard has a lot to do with it. it's a very minimal investment and i've been really happy with it. i truly feel it's helped extend the life of my car.

Lubegard additives are awesome products. Oil additives provide extra protection.

I have been a user of Lubegard Red transmission additive for many years, so I decided to try the Bio/Tech Engine Oil Protectant for the first time. I added it to the engine in my wife's 2011 Toyota Sienna when I did a recent oil change at 100k miles. This van has the 3.5L 2GR-FE V6, and I've done 10k mile oil changes using 0w-20 full synthetic since new. The engine has always been reliable and uses no oil between changes. About 1,000 miles after this oil change my wife pulled into the driveway and I see a long trail of motor oil being left on the pavement behind her. I check the oil and there is nothing showing on the dipstick. My wife claimed that the oil pressure warning light never came on and that the engine sounded normal. I crawled underneath and determined that a rubber hose between the engine and the oil cooler had developed a pinhole leak which had coated the entire undercarriage with motor oil. I had the van towed to a Toyota dealer and they said that this is a fairly common problem with the 2GR-FE of that era, and that Toyota had updated the part with steel hard lines. This hose repair was completely covered by an extended warranty on that part with no cost to me. The best part is that the engine seems to have survived the oil leak unscathed. I don't know how much motor oil was still left in the engine, but there was a lot of it on the ground. The engine runs and sounds exactly the same as before. Now I can't say for sure that using the Lubegard additive prevented a tragedy in this case, but I do believe that it helped to keep the engine protected during this oil loss problem. I will continue using this Lubegard product in all of my engines from now on for the peace of mind that it brings. Update 05/01/23: I just did the 130k mile oil change on this van and the engine is still running great! Of course, I put in the Lubegard Bio/Tech additive like always. It is a great product and I now use it in all of my engines. I've found that it is cheapest on Amazon in the 32-ounce size and have been buying that recently. Update 08/12/24: The Sienna recently had another oil change at 150k miles and everything is still just fine. The engine runs smoothly and uses no oil between 10k changes. I'm continuing to use the Bio/Tech even though the price has increased (like everything else). By doing my own oil changes I save enough to offset spending more for such a great product.

So this is one of two additives that a well respected oil guy recommends. It can actually provide the additives that are lacking in modern oils that in many cases actually cures ticks and engines knocks, depending on the nature of those ticks. This product is loaded with EP additives, which when you have metal out of tolerances the engine provides the conditions needed for the EP additives to plate. It is science, not hype. Many engine run quieter, that is why. The best part is the moly is the latest moly that is oil soluble, so this becomes part of the oil and not just suspended in the oil like other moly, of course in those additives the moly can fall out of suspension and cause issues. So I knocked a star off because it leaked, like several ounces, but I'm still keeping it.

My Chevy is over a decade, 150k plus and runs great. Use this every other oil change, but I also only do like 800 a month. Some off roading and curb stuff bc I live in the country and things to do require it... Just had the trans rebuilt, all the typical seals, crank pulley, front and rear mains, belts, plugs, wires, purge, cooler lines, oil pan, pressure valve, that dumbbell valve, the whole 9. He runs like a champ. Valve covers were clean, no heavy build up slight varnish, plugs were not oil fouled. Oil pump did not need replacing and tube screen was clean. No metal in the engine. But tons of metal in the trans. Lol This stuff and essentially ALL Lubegard products are INCREDIBLE! I work in an auto shop, we use all sorts of their products for different things. Like the shudder stop for those that have neglected their maintenance, but are getting it done and just need some extra 'time' on their unit. I swear by this stuff. And their install grease. Transtar also sells this if you need it fast and you have a local one by you. I think they may also ship to non repair customers, like the public, not just commercial.

Das kann ich nicht beurteilen, aber was zu erkennen ist, dass mein Auto mit Autogasanlage beim erstmaligen Kaltstart nach einer Autogasfahrt auf Benzin immer ausging, wenn man nicht sofort auf das Gaspedal gedrückt hat. Dies ist nun Vergangenheit, der Motor geht kurz mit der Drehzahl herunter und fängt sich ohne nochmals angelassen werden zu müssen. Einen Verbrauchsvorteil kann ich nicht wirklich nachweisen, wenn dann reden wir von max. 0.1 l, da hatte ich mir mehr versprochen nach dem enthusiastischen Bericht der Schweizer Tester.

2011 Dodge Ram 1500 w/ 5.7L Hemi. Quieted the Hemi tick pretty much immediately. No long mileage review (<100 km) yet but I bought another bottle for my 19 Highlander. For the next oil change. I suggest running Sea Foam through the crankcase 200 to 300 miles prior to the next oil change on your gas engine. This will clean out some gunk, varnish and any particles can get trapped in the old filter. Just don't go past your oil change interval you don't want to run with a clogged/plugged oil filter. I just heard about this stuff and I think it will help with engine wear too. Not sure about better mileage yet and I won't extend my oil change interval as it isn't worth it to me. This bottle is cheap insurance vs an engine rebuild. There are good YouTube videos that show how well this stuff works. I just wish pricing was similar to US pricing as it seems to be much more expensive here in the Great White North (like double).

My engine's power increased by 350%. The Camry now has 540hp. At the same time my mileage went from 32 miles/gallon to 56 miles/gallon. Incredible stuff.

Another great product by lubegard. This one really works long term. I use a little portion at every oil change on my mustang. Over 500k km and no issues and no overhauls or leaking gaskets! They do make another version of this product for turbocharged engines.

lube guard benutze ich schon seit Jahren, habe nur gute Erfahrungen damit gemacht. Motor läuft ruhiger und Kühler
