I wonder how a 2021 snow blower will look like...

While I wait for the snow, what about the fuel?

Happy holidays every one! ... bought the toro 1028 OXE back in October, right after the very first early snow storm. Was not able to try it in snow... I added the startron stabilizer And filled up the tank with 93 octane. I tested the new baby, showed off without spinning augers... But now it's a long time unused. My question is: is it okay for the fuel to sit in the carb for such a long time? Thanks!

From page 15 of the 1028 owners manual, "Fill the fuel tank with fresh unleaded regular gasoline from a major name-brand service station (Figure 26)." Typically, regular unleaded gasoline has an octane rating of 87 depending on elevation. The detergent level is independent of octane level.

The all told me that the ECU will detect the octane level, and will adjust the engine to it. The sequoia/ tondra can be fitted with the TRD high performance kit, which includes bigger fuel injectors, Air Intakes, etc... And then you should use higher octane, becouse the engine is going to compress up to 9:1 instead of the standard 8:1.
The engine's knock (ping) sensor will monitor how the engine is running, yes. The ECU may try to advance the ignition timing, to produce more power. Higher octane gas will allow the timing to be advanced more, without knocking/pinging. If you run lower octane gas, the ECU will retard the timing to avoid knocking. You might see less power and reduced mileage. I had a car that recommended premium. When premium got to a level that I thought was unreasonable (~$1.80, as I recall. Clearly this was a number of years ago ), I switched back to regular. The engine automatically adjusted, and I could feel that it had a bit less pep, and my mileage dropped a little. But it was still cheaper. But the engine cannot, so far as I know, change the compression ratio on the fly. The only ways to do that that I can think of would be to change the head, pistons, or maybe the crankshaft. But I don't think the compression ratio can change while you're using it.

How does forced induction change an engine's compression ratio? It doesn't impact the bore or stroke of the engine.

Just to make sure we differentiate..... A car may or may not have computer adjusted timing, to maximize performance to the octane rating. Now I seriously doubt my SB has a computer chip in it ... correct me if I'm wrong... so using the recommended octane is highly recommended.......
