5w30 Synthetic Oil Reviews

1. Valvoline SynPower

Valvoline maintains extremely high standards for their flagship synthetic 5W30 oil, adding superior detergents and protectants to their Group IV stock base oils.

When things get hot in your engine, your valves and pistons are fully protected even with the cold-start friendly lower viscosity rating of a 5W30 blend.

EDITOR'S RATING:

Valvoline SynPower review

With the industry demand increasing for high-efficiency motor oil and more and more engines requiring specialized synthetic only oil, Synpower easily meets the demanding requirements of many manufacturers’ more stringent lubrication requirements.

Lower viscosity also means that if you are running a turbocharger or supercharger on your engine, your oil can withstand the higher temperature extremes that come with high performance parts, too.

Best of all, the blend of additives ensures that your engine stays sludge and varnish free for vehicles under 125,000 miles, improving or maintaining your fuel efficiency and the overall life expectancy of your motor.

While this is an excellent choice for newer vehicles with less than 125,000 miles on the odometer, older cars will most likely benefit from the high mileage blend of Synpower oils due to their superior detergent additives and protectants that are not present in the standard Synpower blend.

Always follow manufacturer recommendations as described on the container when purchasing synthetic oil for your car.

Liqui Moly Longtime High Tech Review

High-performance designers like Porsche, BMW, and other German automakers recommend Liqui Moly for use in their vehicles due to its superior performance under the extreme stress of high performance motors in some of the world’s fastest and best engineered cars.

While it may be a bit more on the pricier end of the spectrum for engine oil, it definitely provides the quality sludge and varnish protection that a high-end performance engine demands over time regardless of whether or not you push it to the limit on a regular basis.

This is definitely a must-buy for fans of German turbo or supercharged motors as well, especially given the extremes to which they push the multi-valve engine designs on modern German automobiles.

Pennzoil Ultra Platinum review

Thanks to the Pennzoil revolutionary production processes, the additives and detergents in this fully synthetic oil clean and protect your motor better than almost any other high performance motor oil on the market today.

Pennzoil stands behind their product 100 percent too, claiming it keeps pistons 65 percent cleaner, adds an extra 550 miles on average compared to engines not cleaned and maintained with their product, and helps guard against a loss of horsepower over the lifetime of your vehicle.

Also, thanks to its significantly lower viscosity, this synthetic oil also offers some of the best available friction protection money can buy.

Most important of all for gearheads and tuners though, this synthetic oil is an excellent choice for use in turbo and supercharged motors, offering the high temperature extreme performance such motors demand of their motor oil. All in all, Pennzoil makes a fantastic product with few (if any) drawbacks.

Castrol EDGE Extended Performance Review

Castrol puts so much faith in their premium synthetic product that they actually guarantee it for up to 15,000 miles between oil changes.

As one of the world’s leading manufacturers of racing performance motor lubricants, that is saying quite a lot.

If you do a lot of towing and hauling over long distances or your vehicle spends long periods of time idling or in commuter traffic, this is the synthetic 5W30 you want in your car.

Castrol’s highly specialized blend of additives in their Fluid Titanium protectant provides 5 times the performance of other synthetic motor oils when it comes to keeping your engine safe and operating at peak efficiency even over extended periods of time.

It also offers the best possible sludge and varnish deposit protection money can buy, and numerous professional and home mechanics swear by this stuff when it comes to reducing motor noise and cleaning out older engines as well.

As the 5-liter bottle would indicate, this is truly the gold standard of synthetic motor oils, and Castrol has the field-tested performance to back it up.

Popular with racing professional teams and high performance amateur mechanics as well, Royal Purple definitely sets high standards for their low viscosity synthetic oils, and their track record for maintaining high performance under duress even in the most demanding conditions remains untarnished for decades

In terms of keeping your pistons, valves, and other engine components valve and sludge free, Royal Purple 5W30 coats all exposed engine components in a fine microfilm of highly specialized lubricant, keeping all moving parts functioning smoothly even as your oil levels diminish over time with the extreme heat of warm weather driving and turbo or supercharged engine kits.
