A fifth generation manual transmission Prelude would fit the bill nicely. Very reliable, and handling is great even without bolt-ons (dual wishbone suspension). Lots of bolt-ons available (suspension, exhaust, intake, but not really needed. The most fun to drive car Honda ever made, other than the S2000. I’ve been driving one for 12 years.
Higher octane gas has lower energy capacity – that’s why higher octane gas does not detonate early in the engine (knock). However if the engine is knocking, the ECU will retard timing and you will lose power. So you want the octane to be as low as your engine will handle without knocking for the best MPG.
My engine requires 91 octane (as per manufacturer), but when I put 89 in it when weather is cool or cold, I do get a little better MPG and of course a little more power on the highway. Not sure if the engine knocks a little in city driving on 89, but I haven’t tried it as knocking is bad for your valves.

Thanks Eric, wish I knew how the engine should sound that needs adjustment. Also how to find an experienced tech that can do these well.

The block will be filled with water so it’s better to use undiluted. Filling with 50/50 after garden hose flush will mean the actual concentration is 70/30 or something. When I did garden hose flush, I emptied most of the water from the block with air pressure into the upper hose.

Here’s the thing about sticking to manufacturer’s recommendation on oil change interval that I don’t understand. If it is given in the manual for conventional oil, why should one still change synthetic oil at the conventional oil interval? That doesn’t make any sense. I’ve been using synthetic since about 7.5k, which has about 150k miles on it now with around 10-13k between changes. The recommended conventional oil interval is 7.5k. No issues so far. New cars with recommended synthetic oil fill have even longer drain schedules. BMWs around 16K. If you want to know for sure, you can use oil analysis service that will tell you the correct oil change interval with your specifics.
The leaking seals issue is with cars that were made with incompatible rubber seals decades ago.

But how do you know that it actually works?? Do you use an oil analysis service to find out there is less wear on the engine? This additive might not hurt, but it may not help either. Without analysis of the used oil you’ll never know for sure.
