I have a late model Vios. It runs on Gasohol 91. In my part of the woods there are petrol stations, which have Gasoline 91 and no Gasohol 91. Is it ok to switch to Gasoline 91 now and then, when there is no Gasohol 91 available and change back to Gasohol 91 when available? I know the issue has been beaten to death on various threads, but I'm still confused. Some people tell me I can use any fuel available, others tell me by doing so will do damage to the engine and the seals. Thanks.

Putting gasohol in a older car not designed for it is the problem and will cause damage.

Indeed ^^^, but putting regular gasoline in a newer gasohol capable vehicle will cause no problems whatever

Indeed

a new Vios can run any LOS petrol/ gasohol or a blend of them, except E85 containing 85% Ethanol

a dose of petrol now and then is actually healthy as it lubricates parts in pump/injection system

We use gasohol in our VIOS for our weekday "go to work" city driving, and pay the extra for a tank of benzine when we go out of town / highway driving. I notice an improvement in performance which makes a long trip more entertaining, and provides a little more "confidence" when extra power is wanted (needed) for overtaking other cars and trucks.

Not correct

fuel is not always the same 91 gasohol E10 in one pump can be different from 91 gasohol E10 in another pump. different brand names and different qualitys each supply.

Most choose the least expensive fuel car can handle, and its healthy to provide better juice on occasions

Some cars have knock sensors, and ECU adjusting engine to run whatever fuel is provided. Higher octane, more power and less consumption

In general E10 is good as it keeps engine internals clean, but on occasions its good to recieve some good old petrol to lubricate things better

ecu's can learn and adjust themselves to fine tune the engine call mapping, not sure about the VIOS but certaintly in other cars, now does this do any harm ? unlikely
