I work at FORD.
1. While premium is “recommended “ for MAXIMUM power, it’s not required. And the loss in power is minimal. In fact, most don’t notice much difference. I’d say that 95% of the owners use regular which is acceptable by Ford. Almost every engine built in the last 20 years is equipped with a knock sensor. So for the most part, spark knock is a thing of the past unless premium is REQUIRED, and the customer uses regular. But as stated earlier, premium is not required for most engines. Turbo or not.
2. Turbos are more complex and add more heat. But the engines have oil coolers. And smart oil life meters which indicate the oil change intervals based on YOUR driving conditions. Most customers require an oil change around 6000 miles. The new turbos are light years ahead of the trouble prone turbos of the 70’s and 80,s. We’ve already seen some with over 100,000 trouble free miles . I expect them to greatly exceed that.
3.While some manufacturers are moving towards cvt’s Ford does NOT use them and has not since their disaster in some of their 2003-2006 models. They do have a trouble prone dual clutch automatic. But they don’t use it in ANY of their turbocharged vehicles . But rather they use a beefed up version of their transmissions used in the base engines. So far, very reliable.
4 . Maintenance costs are NO DIFFERENT unless they break down which is rare as far as the engines and transmissions.
Trans fluid changes at 100k , NO external fuel filter. , hoses commonly last for well over 100k. Belt service interval is 100k . Most still look good even then. . Coolant 150k. Spark plugs 100k . No plug wires.
Truth be told, we mechanics are not making the money we used to make because the cars simply are more reliable than in the past. AND there is hardly any maintenance required.
