I saw 1mpg drop from the dealer once putting in 5-20 vs 0-20.
It was instantly, one tank of fuel, 1mpg less.
As for 0-20vs0-30 I can't tell you.
I live in Mi, even in summer, if it's really hot it may hit 90, tops 100 for a few days out of the year. Short drives.... I am more than happy with 0-20 and in actuality I found my engine is quieter with 0-20 than it was with 5-20.
To each their own. I will tell you that manufacturing tolerances are a lot tighter now than ever before when you are talking about internals of an engine. Engines now last far longer than they used to on average, and they also call for thinner oil, and synthetic blended at the least. Oils have also came a really long way since when I was 16 and my grandpa handed me a case of 15-40 oil for my mustang with 80k miles that was noisy and said it would quiet it down... Then again, back then fuel was .90/gal. so fuel economy didn't matter one bit.
Food for thought. 10 years ago it was not uncommon to have a 2cycle piece of equipment that ran 32:1 or 40:1. Now they are all 50:1, you can run any 2 cycle outdoor power equipment at 50:1 if tuned properly and will not have an issue and actually will have less issues because you will not have clogged spark arrestors nor will you have clogged exhaust ports or stuck carbon'd up rings (assuming you run good fuel). Hell, with amsoil you can supposedly run same equipment at 100:1. AND yet everyone is worried about 0-20 vs 0-30... We are literally talking that the oil has came so far that you can run an engine that lubricates itself with oil mixed in the fuel on less than half the oil it recommended years ago when it was a high tech engine...
Food for thought.
Carry on.
