The Best Engine Oil Additive To Improve Performance of Diesel & Petrol Engines

Everyone wants to ensure their vehicle is running at it’s best. The most important factor to an engine running smoothly is the oil contained within. Getting the best quality oil and right viscosity is undeniably of great importance, but you can actually take it one step further than this. In recent years multiple products have begun to surface that promise better engine performance and longevity.

Engine oils all contain additives to improve their functionality. Manufacturers often use these chemical mixtures however, only in small amounts however to keep costs down and ensure that they can offer products to rival other brands in the sector. The constant push for cheaper oils and relentless pursuit to bring new products to market means that engine oil brands have little choice but to offer basic level oils that appeal to a large customer base.

Though often confused, performance enhancing additives and oil stop smoke products work similarly but give differing outcomes. For more information and the best stop smoke products check out our article here.

How an Engine Oil Additive Can Improve Performance

For those that are enthusiastic about their vehicle and take extra care in maintenance, you can enhance the oil in your vehicle’s engine for only a little extra outlay. The additives listed below are should be added at the next oil change (with standard engine oil) to enhance lubrication and corrosion resistance.

Friction modifiers are used to decrease wear between internal metal components, while also reducing extra heat induced by friction within the engine. Stabilizer elements help to ensure that the oils viscosity is not affected during extreme temperature changes, ensuring a better running engine after numerous heat cycles. Finally, some oil additives actually provide a cleaning affect, working to remove baked on carbon deposits to enable improved oil flow and more efficient running.

Next up, ZX1, with their flagship product, the micro oil treatment additive. ZX1 specialise in their friction modifying formulas that work to enhance the friction properties contained within engine oils, but without reducing the quality or leaving unwanted particles than can clog filters and cause untold damage. Their product comes at a higher price due to the smaller size of the company and more dedicated testing behind their additive offerings.

Extra lubrication can give results of reduced emissions and improved fuel economy, thanks to more efficient combustion, with less energy wasted due to internal friction. Unlike rivals, ZX1’s additive does not mix with the oil, it stays as a separate fluid, allowing it to coat internal engine components as it will not be constantly shifted around the engine. This has the secondary effect of maintaining a lasting protection for your engine, even after multiple oil changes.

These features have led to the little-known brand becoming one of the UK’s best-selling, performance enhancing oil additives. The product only needs renewing every 25,000 miles, while other brands generally need to be added with each oil change.
