Piston Slap: Focusing on Turbo 93 Octane Tunes?

Mark writes:

Sajeev,

Thanks for the recent advice on winter tires & wheels for my new Focus ST. I took delivery of the car two weeks ago and I’m having a blast. The first thing I did when I got it home was take Bark M’s advice and sign up for the Octane Academy.

So here’s another question: What’s your take on fuel octane and the ST?

Hi Sajeev,

This is the second question I’ve asked on here, and while I didn’t even follow the advice I received last time and here I am again! Last time I was asking about a sporty car, and I ended up getting a 2007 Ford Ranger, 2.3L, 5 speed, with all of 35,000 miles on it. It is a regular cab with nothing extra on it, a real throw back, manual windows, no AC, a nice basic truck with nothing to go wrong right?

Wrong.

Dear Sajeev,

I own an 06 Sonata with the 3.3. It is paid off and has 79,000 miles on it. I love this car.

  • Probert They already have hybrids, but these won't ever be them as they are built on the modular E-GMP skateboard.
  • Justin You guys still looking for that sportbak? I just saw one on the Facebook marketplace in Arizona
  • 28-Cars-Later I cannot remember what happens now, but there are whiteblocks in this period which develop a "tick" like sound which indicates they are toast (maybe head gasket?). Ten or so years ago I looked at an '03 or '04 S60 (I forget why) and I brought my Volvo indy along to tell me if it was worth my time - it ticked and that's when I learned this. This XC90 is probably worth about $300 as it sits, not kidding, and it will cost you conservatively $2500 for an engine swap (all the ones I see on car-part.com have north of 130K miles starting at $1,100 and that's not including freight to a shop, shop labor, other internals to do such as timing belt while engine out etc).
  • 28-Cars-Later Ford reported it lost $132,000 for each of its 10,000 electric vehicles sold in the first quarter of 2024, according to CNN. The sales were down 20 percent from the first quarter of 2023 and would “drag down earnings for the company overall.”The losses include “hundreds of millions being spent on research and development of the next generation of EVs for Ford. Those investments are years away from paying off.” [if they ever are recouped] Ford is the only major carmaker breaking out EV numbers by themselves. But other marques likely suffer similar losses. https://www.zerohedge.com/political/fords-120000-loss-vehicle-shows-california-ev-goals-are-impossible Given these facts, how did Tesla ever produce anything in volume let alone profit?
