Product Details

Sierra 118-9555CAT-4 is a premium semi-synthetic 5W-30 marine engine oil designed specifically for outboard motors, stern drives, and inboard marine engines. This case contains five quarts of advanced formula oil that provides superior protection in harsh marine environments.

Key Features:

  • Semi-synthetic formulation combines synthetic and conventional base oils for enhanced performance
  • 5W-30 viscosity rating provides excellent cold-start protection and high-temperature stability
  • Specially formulated to resist moisture contamination common in marine applications
  • Helps prevent rust, corrosion, and deposit buildup in marine engines
  • Meets or exceeds FC-W Catalyst Compatible oil specifications
  • Contains 5 quarts total (individual quart bottles)

This FC-W rated oil is compatible with catalytic converters and provides the protection modern marine engines require. The semi-synthetic blend offers better performance than conventional oils while remaining cost-effective for regular maintenance intervals.

Easy to order, great price and fast shipping. Great first buying experience.

I'm a first time buyer of your company and was impressed with the service. I Goggled what I needed..... your company website popped up, and I placed an order. Very easy and stress free! Will be buying from you in the future. Thanks!

ok.....should have been a new customer discount!

Did not receive order confirmation or shipment notification. Called customer service. They suggested looking in my email spam folder. Both emails were there. Everyone else was out of stock on my item. You guys had it and shipped very quickly. Thanks!
