Don't do anything too rash.

We have a warrant here once a year for older cars or two yearly for up to ten years old. About $55 for a warrant. Rego is roughly $10 a month. BUT this is the kicker, fuel 91 octane was up to 2.30 a litre pre covid, now about 1.90 litre. Not gallon,

I made for me an unusually smart decision when the sub prime disaster hit the UK. I left our pensions in place but liquidated our savings and place them into Government premium bonds. Your capitol sum only decreases with inflation. Each month there is a drawer, the prizes are from £25 to £ 1 million. We regularly win small amounts that have generated a tax free return of now around 5%. Premium Bonds
How does that affect performance? Our standard petrol in the UK is 95 octane, and is currently around 1.09 per litre. This is the minimum UK cars are tuned for. Premium petrol is 99 octane, cost around £1.40 per litre. My brain is too weary to compute litres to US gal/UK gal and £/$. Maybe later. I generally run our daily cars on cheap supermarket fuel, switching to premium, branded fuel every three or four fill-ups.
He was one of the few oil company engineers to testify in Congress in favor of banning lead from gasoline (an octane booster). He made a few enemies, but his company (Gulf Oil at that time) backed him up, and continued to give him promotions. Gulf Oil was a good company. All the top executives were engineers -- not MBAs like they are now.
Ah, that explains it, thank you CD. Now I know who to turn to with my petrol related queriesThe UK is using the RON (Research Octane) standard. The US used the MON (Motor Octane) standard years ago, and switched to the AKI (Research plus Motor divided by two). So, US (and Canadian) gasoline will show 4 to 6 points lower octane ratings than UK petrol.
So, your 99 octane and my 93 octane are almost the same. Cars sold in the US that require premium gasoline are tuned in their ECUs (Engine Control Units) to run best on 91 octane. My 93 octane gas doesn't really benefit me, as the ECU is not tuned to take advantage of that extra octane. Some Americans buy octane boosters to bump up to 95-plus octane, which is a waste of money, because the ECU doesn't know what to do with it. In modern, computer controlled engines, knocking is virtually unheard of. The ECU can sense knocking, and change the timing in a fraction of a second.
My dad is a retired chemical engineer and oil company executive, and one of the few thing he liked to talk about was his work. So, I learned a lot more about petroleum than I ever needed/wanted to know.

. The Gulf brand still seems to feature in motor racing sponsorship over here, but I can't remember the last time I saw a Gulf filling station.
