The Most Reliable Engines Ever Built By Mazda
2.0L Skyactiv-G
Since its introduction in 2011, the gas-powered Skyactiv-G engine line has generally been
proven to be remarkably reliable.
The 2.0L version has been featured in best-selling cars like the ND MX-5 Miata. One Miata owner racked up more than 163,000 miles without issue in less than five years.
1.8L F8
The F8 engine remained in production in various Mazda and Kia models from 1982 to 2005 and first appeared in the Mazda 626 and Capella.
Although it wasn’t as exciting as other engines, the F8 was a reliable workhorse that could withstand the abuse and high mileage of powering a commercial vehicle.
1.8L K6
Despite being the smallest in the K-series, Mazda built the 1.8L V6 engine tough and equipped it in the MX-3 sports coupe.
It was developed close to the peak of Japanese over-engineering, so its high-strength steel and aluminum construction was considerably stronger than needed.
2.5L Skyactiv-G
The 2.5L turbocharged version of Mazda’s gas-powered Skyactiv engine's exceptional design won a Wards 10 Best Engines award in 2017.
The design features a unique butterfly valve in the exhaust that helps the turbo spool quickly, giving it quicker off-the-line performance than many of its rivals.
2.0L LFF7
While not a performance engine, the 2.0L LFF7 engine has a reputation for lasting years with minimal upkeep and impressively low maintenance costs.
It had between 140 and 150 horsepower and up to 140 lb-ft of torque, serving as the base engine option for the Mazda6 and Mazda5. The engine would eventually be retired in 2011.
