## Overview

Lubegard 30916 Heavy Duty Engine Protectant uses cutting-edge Liquid Wax Ester (LXE) Technology to reduce engine friction by up to 29%, extend oil life by 30%, and improve fuel economy—all without voiding OEM warranties. Designed to supplement modern motor oils, it enhances anti-wear properties, lowers engine temperatures, and optimizes horsepower, making it a must-have for professionals seeking reliable, long-lasting engine performance.

## 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: Smooth and quiet - My car has a noisy valvetrane. There's nothing wrong with it, it's just a fact of life with the very complex variable camshaft system Nissan used to squeeze every ounce of power out of this V6 without adding a turbo. Nissan makes their own "ester oil" that sticks to the valvetrane and helps reduce the noises these engines are known for, but at over $12/qt for a semi-synthetic, it's quite pricey. Instead, I use half a bottle of this and a jug of whichever full synthetic is on special at the store. Cuts the cost of my oil changes in half.

## 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.

### ⭐⭐⭐⭐⭐ 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.
