Most all "Stock" gasoline engines made in many years (LIke the 1970's) were designed to use Regular grade. And at some point in the 70/80's they made them all use No-Lead, and subsequent to that leaded regular has become very hard to find.
ANY "Stock" engine made this century should be happy with regular no-lead UNLESS it is in need of service.
What can happen is over time carbon deposits build up in the combustion chambers and you may start to hear a bit of "rattle" (Pre-ignition knock) which goes away if you upgrade the fuel to mid or premimum.
HOWEVER, this means you need service, MAJOR service.
ON older engines with breaker points as the timing changed due to wear of the system.. Fuel needs sometimes changed.
However... Modern engines use a very very precise hall effect sensor. it does not "Wear" like points did.
You are of course speaking of gasoline engines used in Class A and C motorhomes, not all vehicle engines at large. There are a great many engines outside of motorhomes that REQUIRE fuel with an octane rating of 91 or more. I own 2 of them.
Now the V10 in our motorhome is quite happy on 87 as required by Ford. My GT and my Spyder would not be so happy.
