Hi Jim,

    Most people don't  advise changing brands/types, or weights, etc of oil.
I for one don't see a problem changing, Use the right weight for your
climate, maybe changing weights from summer to winter if your area has a big
seasonal swing. So would I change, yes I would change. Simple because of the
cost factor! Also synthetic oils are thinner and will find a way to leak
where as dyno-oils have a better chance of staying put. Again this is just
my opinion, take it with a grain of salt!
    You know this is going to start a major flame war! So just do the leg
work and make up your own mind
