Compatible with all diesel and gasoline engines, it enhances all major motor oils by replenishing depleted anti-wear additives, reducing engine noise, and improving fuel economy. Trusted by professionals and enthusiasts alike, this 15 oz. universal additive ensures smoother, quieter, and longer-lasting engine performance. ## Description LUBEGARD ENGINE OIL PROTECTANT contains Liquid Wax Ester (LXE) Technology, the lubrication system of the future. Specifically formulated to minimize friction and wear, also to keep the oil cooler in today’s more complicated engines. All modern engine oils contain a highly refined petroleum or synthetic base oil which is fortified with additives to meet motor oil performance specifications. Even so, dated specifications may not represent the level of performance needed by a new engine design. A new oil may not contain sufficient additives such as ANTI-WEAR agents or ANTI-CORROSION compounds even though it passes all the tests. Furthermore, these protective compounds are depleted when the oil is in service. The solution to this protection gap is LUBEGARD ENGINE OIL PROTECTANT which supplements and enhances the effectiveness of the additive system already present in the oil. LUBEGARD replaces the depleted or insufficient additives and adds LXE wear protectors and friction reducers which are unavailable in any oil. Minimum friction means maximum mileage; minimum wear means maximum service. Blends with ALL motor oils currently produced, including API; SJ, SJ/EC, CG- 4, CH-4, SE, SF, SG, SI, CC, CD, CE, SL, SD, SM and CF motor oils. Helps reduce smoking by restoring flexibility to valve stem seals for improved sealing, also providing outstanding upper cylinder lubricity as it frees up sticking rings. In addition, LUBEGARD increases the thermal and oxidative stability of motor oil to prevent creation of sludge and deposits. There is a need for improved oil additives for protection and mileage in view of the rapid technological changes in modern engine design. LUBEGARD provides a concentrated package that fulfills these deficiencies (without adding ZDDP, Chlorine, inappropriate sludge building additives like PTFE or solid lubricants such as Teflon, graphite or molybdenum disulphide.) LUBEGARD with LXE Technology will carry your engine through to the future! Also use to extend the life of small 4 cycle engines such as; lawn maintenance equipment, motorcycles, snow mobiles, etc. ## Features - Optimizes engine horsepower and performance - for use in all diesel and gasoline engines - Improves fuel economy by reducing friction in your engine - Protects and extends oil life by 30% - Reduces wear on metal components, thus increasing part life / Eliminates lifter and other objectionable noise on startup, especially in cold weather - Improves anti-friction and anti-wear properties of all major oil brands to meet requirements of all vehicles, including older and high performance models - Reduces hot engine oil temperatures / Ensures smoother running engines / Inhibits oxidation and extends engine oil life - Reduces oil and fuel consumption - For use in all diesel and gasoline engines (blends with all motor oil currently produced) - Optimizes engine horsepower and performance - Protects and extends oil life by 30 percent - Eliminates lifter and other objectionable noise on startup, especially in cold weather ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B001DKJWEG | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #32,326 in Automotive (See Top 100 in Automotive) #51 in Engine & Oil Fluid Additives | | Brand Name | Lubegard | | Compatible With Vehicle Type | Truck | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (618) 4.7 out of 5 stars | | Global Trade Identification Number | 00083137309017 | | Item Weight | 50 Grams | | Liquid Volume | 15 Fluid Ounces | | Manufacturer | Lubegard | | Manufacturer Part Number | 30901 | | Model Number | 30901 | | Sae J300 Viscosity Grade | 60 | | Size | 15 oz. | | Unit Count | 15.0 Fluid Ounces | | Upc | 083137309017 | ## Product Details - **Brand:** Lubegard - **Liquid Volume:** 15 Fluid Ounces - **Package Information:** Bottle - **SAE J300 Viscosity Grade:** 60 - **Vehicle Service Type:** Truck ## Images ![Lubegard 30901 Bio/Tech Engine Oil Protectant, 15 oz. - Image 1](https://m.media-amazon.com/images/I/81zmUYnn84L.jpg) ![Lubegard 30901 Bio/Tech Engine Oil Protectant, 15 oz. - Image 2](https://m.media-amazon.com/images/I/81y-osynu7L.jpg) ![Lubegard 30901 Bio/Tech Engine Oil Protectant, 15 oz. - Image 3](https://m.media-amazon.com/images/I/717BMFkRBoL.jpg) ![Lubegard 30901 Bio/Tech Engine Oil Protectant, 15 oz. - Image 4](https://m.media-amazon.com/images/I/71NkMr2X9eL.jpg) ![Lubegard 30901 Bio/Tech Engine Oil Protectant, 15 oz. - Image 5](https://m.media-amazon.com/images/I/71Jvf6K7xRL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: I have a tundra with a 2 micron oil bypass filter. Will any of the contents of this product be captured by the filter?(Normal filters are 20 micron)** A: Hello - Our Bio/Tech does have molybdenum that is organic and soluble. A 2 micron filter catches everything including additives in some instances. People have been pushing these types of filters that filter below 5 micron (OE's tried 5 micron in automatic transmissions but found they quickly loaded and went to by-pass and have since been discontinued) and is why these types of filters operate in a by-pass mode. They quickly load and no longer work. You will more than likely have the same experience. If you need further assistance or have additional questions, please give us a call at (800) 333-5823, or send us a message at Contact@lubegard.com Thanks & Happy motoring **Q: can u put all 32 Oz into the engine or haves to be a limit ?** A: It's 3 oz per quart of oil, so for most passenger cars that will be half of a 32 oz bottle or 1 entire 16 oz bottle. Adding more than the suggested amount isn't necessary and just a waist of money. If your car takes 5 quarts of motor oil then just add 16 ounces. **Q: is Lubegard 30902 Bio-Tech Engine Oil Protectant fits my honda accord 2.0 with mobil ep 5w30 oil?** A: If you can run Mobile One EP 5w-30 10,000 miles without needing to add any oil, then you don't really need Lubegard.I will say their red and black bottle atf additives work wonders on honda transmissions. I took my accord to 265,000 miles on it.p and it still runs just fine, for its new owner. **Q: Does anyone have a recent virgin oil analysis? ty** A: no ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lubegard Bio/Tech Engine Oil Protectant may have saved the day! *by on Reviewed in the United States July 19, 2020* 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.Update 04/08/26: I just completed the 170k mile oil change (still 10k intervals) and everything is perfect. This 3.5L V6 is an amazing engine and still runs like new. It doesn't use any oil between changes and doesn't leak any oil either. I'm still using the Lubegard additive and have just purchased some more. It's nice to see that the price has come down somewhat. I really wish Toyota still offered this V6 engine in their new vehicles. Our 2024 Grand Highlander has the 2.4L four-cylinder turbo, which has adequate power, but it's not in the same league as the 2GR-FE as far as being smooth and quiet. Folks, the bottom line is I still highly recommend the Lubegard Bio/Tech because it is a fantastic product!! Thanks for reading. ### ⭐⭐⭐⭐⭐ Anything LubeGard is very good.
