So where can I find ZDDP additives?
Not really sure if the ZDDP blows converters or just renders them useless, that seems to be what I have seen in other articles.

I was born into the oil business. My family has been an oil distributor for 28 years. I think it all comes down to personal preference unless you read into things. Cheers to all, use what you want and just have fun boating! If anyone needs info on Mobil, you know where to find me.

Does Redline make marine specific gear oil? I'm wanting to put a synthetic in my Kaama drives.

Marine? I've been using Redline Heavy Shockproof in my Bravos for 8 years. 600hp, 41' boat, big NJ waters and never broke a drive. 50 hour change interval on the oil.

Mobillube SHC 80-140 or the 75-90. It gets used in a lot of the APBA boats and goes into all the IRL and NASCAR's

The best war stories are Redline.....just add it in carefully to avoid the potential for air entrapment.
