Mercury 60hp 4 stroke outboard oil analysis.

I'm thinking fuel. Blackstone shows 1.8 % but i think they base that off flashpoint. I'm thinking its higher. Engine may be running a bit rich?

If BS shows 1.8% then it's more like 5%...lol

Please note that I did not indicate the grade/weight of oil on the report; It appears that Blackstone used an estimated flash point base to formulate fuel dilution number.

Yes, BS's method of estimating fuel dilution always greatly underestimates the actual level of fuel dilution.

Why doesn't BS use an industry standard method to determine fuel dilution?

Cheaper...

Cheaper...

But BS is by no means the cheapest UOA kit to buy out there. Yet they use cheaper testing methods and charge extra for TBN?

I will stick to the NAPA UOA test kits.

So knowing this why to people on BITOG still go to BS. Pay more and get less.
