What oil do you use?


Recommended Posts

I stick with conventional oils well racing blends of them Castrol 20w 50 racing or Valvoline 20w 50 racing oil. I have been running those 2 oils for close to 40 year in V8 engines and never had a oil related failure. It keeps good oil psi when hot and is designed to be abused.

Not quite sure why but my owners manual says not to use full synthetic oils in my engine. It's a 6.2L Mercruiser engine. I run full synthetic in my trucks (Mobil 1), but they recommend Mercruiser brand oil. (I know, I know, they're always going to say there oil is the best, but WTH).

I tried full synthetic last year. It got dirty just as fast as regular oil. Trolling is a lot tougher on oils than cruising. When the oil starts to darken, change it. Mine gets changed 2 or 3 times a year. I do a lot of slow trolling. I like Castrol.

Mobil 1, 10w30. Looks new every year when i change it. Just a note. Alot of guys will change oil based on number of hours of runtime on engine. When your boat sits 5 to 6 months out of a year that oil still breaks down just sitting. Change it every season or more reguardless of runtime.
