If you own a Yamaha 4-stroke WaveRunner, you already know that keeping up with oil changes is one of the most important things you can do to protect your engine. For years, Yamaha WaveRunner owners have had one option for OEM-spec engine oil: Yamalube 4W — a high-quality, conventional marine oil trusted by thousands of riders. That all changes now.

Yamalube has officially released a full-synthetic version of their 4W engine oil — a first in the brand's history — specifically formulated for 4-stroke WaveRunner engines. And PWCParts.com is proud to be the first to offer a complete, ready-to-ship oil change kit built around this groundbreaking new oil.

A Historic First: Yamalube Full-Synthetic 4W Oil for WaveRunners

For the first time ever, Yamaha's own Yamalube brand has developed a full-synthetic 4W formula engineered specifically for 4-stroke personal watercraft engines. This isn't an aftermarket substitute or a workaround — it's genuine Yamalube, straight from Yamaha, now available in a full-synthetic formula that delivers superior protection, cleaner operation, and enhanced performance compared to conventional oil.

Full-synthetic oil offers a number of advantages for WaveRunner engines, including better protection under extreme operating conditions, improved viscosity stability across a wide temperature range, reduced engine wear over time, and longer-lasting lubrication. For riders who push their machines hard — or who simply want the best possible protection for their investment — the switch to full-synthetic is a significant upgrade.
