Best 4 stroke oil

[marquette]

we have had a lot of discussion on here about 2 stroke oil but what about 4 stroke oil. i'm getting ready this weekend to change the oil on my 4 stroke. so has anybody had any good or bad experiences with one brand of 4 stroke oil or another? they seem like they are all about $8 per qt though i did see an off brand for $5 per qt. and we have discussed the down side to synthetic in an outboard but i noticed most of the manufacturers now offer a semi synthetic and a dino oil. any body had any experience with the semi synthetic as far as "making oil"?

This is the best article I have come across about 4 strokes that make oil. Sorry, can't help you. I still have one of them ol 2 strokes!

Re: Best 4 stroke oil

thanks for the good read on "making oil" because my motor fits into the long hours of trolling catagory. but it doesn't address the dino/semi-synthetic question.

how many hours do you use your outboard a year? I Run a semi synthetic SH grade oil in my Johnson 4 stroke. No need for expensive full synthetic unless you amass hundreds of hours a year, 99% of people don't use there outboards enough to "use up" the oil additives in 1 years time.

i bought Honda oil today at the dealer. there only was dino oil in the Honda brand. it was $6 per qt. that is just about as cheap as 2 stroke oil today. they had Yamaha, suzuki, mercury and honda 4 stroke oil. honda amazingly was the cheapest. the parts guy had no recomendations as to one being better than the other. he just felt each manufacturer used a different combination of additives blended to their specifications. i'm sure it is just a valvoline/pennzoil/quaker state thing. they all work.
