Designed to supplement modern motor oils by replenishing essential anti-wear and anti-corrosion additives, it keeps engines cooler, cleaner, and performing at peak horsepower. Ideal for professionals who demand reliability and efficiency from their vehicles, this 32 fl. oz. formula is a must-have for every oil change. ## Description LUBEGARD HEAVY DUTY ENGINE PROTECTANT contains Liquid Wax Ester (LXE) Technology, specifically formulated to minimize friction and wear — keeping the oil cooler in today’s more complex 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 Heavy Duty ENGINE 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. 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, or solid lubricants such as Teflon, graphite, or molybdenum disulphide.) LUBEGARD with LXE Technology will carry your engine through to the future! DIRECTIONS FOR USE: Apply 3 ounces (88.7 ml) to each quart (946 ml) of motor oil. For best results use with every oil change. Review: This stuff made my 1995 Dodge Dakota run better, reduced engine noise - There are many oil additives out there that are nothing but "snake oil". However, this IS NOT the case with Lubegard Heavy Duty Engine Protectant. This stuff made my 1995 Dodge Dakota run better, reduced engine noise, improved fuel mileage... good stuff! I'm sold on Lubegard products! And believe me, I've tried them all !! I have no affiliation with this company, just a common person in need of true products! Review: Great product - Always add this at every oil change. Could be overkill but with a Ram 5.7L Hemi engine issues can cost you $$$$$. Much cheaper to buy this and a good full synthetic oil and filter. ## Features - Will not void OEM warranties - Reduces oil and fuel consumption; improves fuel economy by reducing friction up to 29 percent - Extends engine oil life by 30 percent and reduces engine oil temperatures - Improves anti-friction and anti-wear properties of all major oil brands - Optimizes engine horsepower and performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006HI8H90 | | Best Sellers Rank | #147,878 in Automotive ( See Top 100 in Automotive ) #372 in Engine & Parts Fluid Cleaners | | Brand | Lubegard | | Customer Reviews | 4.6 4.6 out of 5 stars (105) | | Date First Available | December 3, 2011 | | Item Weight | 0.01 ounces | | Item model number | 30916 | | Manufacturer | Lubegard | | Manufacturer Part Number | 30916 | | Product Dimensions | 9.3 x 4.3 x 2.3 inches | ## Images ![30916 Heavy Duty Engine Protectant, 32 fl. oz. - Image 1](https://m.media-amazon.com/images/I/41YpMh0FeHL.jpg) ## Questions & Answers **Q: Does this work in an old classic 1950's car?** A: this worked great in all engines i have used it in -best additive i have used **Q: If my truck hold 7 quarts of oil do I put in all 7quarts and on top of that then add 21 ounces of Lubegard?** A: The second answer is correct. Hold back 21 ounces of oil to compensate for adding 21 ounces of Lubeguard. The TOTAL fill will equal 7 quarts. I put 5 quarts of oil in, add the 21 ounces of Lubeguard, then add another 1 quart and 11 more ounces of oil. My truck always comes out right at the full level on the dipstick every time. It's bad to overfill your engine by 21 oz. , I've seen the problems caused by someone doing that. **Q: Is this the same thing as the lubegard 40902 bio/tech engine oil protectant? just different packaging?** A: it comes up as a different part number but I'd be surprised if it's different, the heavy duty is cheaper, works well to save adding a quart between oil changes. **Q: This additive is compatible with full synthetic oil.** A: yes, add 3 oz per qt of engine oil, at every oil change. for 5 qts you would put in 15 oz but subtract that amount from the 5 qts so you do not over fill. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This stuff made my 1995 Dodge Dakota run better, reduced engine noise *by R***R on July 10, 2018* There are many oil additives out there that are nothing but "snake oil". However, this IS NOT the case with Lubegard Heavy Duty Engine Protectant. This stuff made my 1995 Dodge Dakota run better, reduced engine noise, improved fuel mileage... good stuff! I'm sold on Lubegard products! And believe me, I've tried them all !! I have no affiliation with this company, just a common person in need of true products! ### ⭐⭐⭐⭐⭐ Great product *by D***E on June 11, 2024* Always add this at every oil change. Could be overkill but with a Ram 5.7L Hemi engine issues can cost you $$$$$. Much cheaper to buy this and a good full synthetic oil and filter. ### ⭐⭐⭐⭐⭐ Engines do actually run smoother and more and more quietly. *by T***Y on December 12, 2016* UPDATE January 2017: All stated benefits still being 100% accurate, I tried this in my lawnmower (Honda 165cc engine) and it notably quieted the engine. I mean, the wife commented on it. It is also much more difficult to stall now. Same gas. Same spark plug. I'm impressed. Smoke on cold start was also eliminated. This significantly and noticeably quieted the engine operation on my 2013 Ford Explorer 2.0 Turbo, 99 Impreza Outback Sport 2.2, and 2011 Outback 3.6R Limited. All three now have zero valve noise on cold start and idle in virtual silence....with minimal cooling fan activation. Engines seem to rev more freely and there has been a .5 MPG improvement on the Explorer, a .7 MPG improvement on the Outback, and a 1MPG improvement on the Outback Sport. I'm imminently pleased. And, this was added in the proper ratio to synthetic oil (Pennzoil Platinum, PP High Mileage, and Castrol Edge Titanium Gold Bottle)....so the effects are not being minimized. I will continue to update, but I'm extremely pleased. I did not expect such a large improvement on engine smoothness across these three vehicles. ## Frequently Bought Together - Lubegard 30916 Heavy Duty Engine Protectant, 32 fl. oz. - Lubegard 63010 Platinum Automatic Transmission Fluid Protectant, 10 oz. - Lubegard 60902 Automatic Transmission Fluid Protectant, 10 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/13419193-30916-heavy-duty-engine-protectant-32-fl-oz](https://www.desertcart.co.uk/products/13419193-30916-heavy-duty-engine-protectant-32-fl-oz) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
