I'm wondering how many people on here use automotive rather than marine 4 stroke engine oil in their motors?
Suzuki recommends a 10W 40 oil meeting API specification 'SJ' for my 2002 motor and changing it every 100 hours.
This would equate to 3 or 4 oil changes per year.
I wonder if using something like this would cause any harm?

There's huge debates on this subject if you do a google search, but in UK conditions, in real life has anyone had any good or bad experiences of using aftermarket oil?
