How many of you run a full synthetic oil?

Sorry... don't remember the name of the program. Saw it last few months. It was British and they review hp loss on a dyno after high mileage, how to recover (such as tune-up type stuff), and even with excessive miles, the loss of hp from loss of compression was nothing near that high. IIRC it was more like 1hp/year (10hp over 10 yrs, think the car was in excess of 100k), although it's not the years, its the miles.
Sorry I can't be more specific. I'll try to hunt sometime.
It surprised me a bit that a number of sources cite ticking with all synth. Ford has done OHC for many many years. They recommend synth-blend for a reason.

For example, the Nissan 3.0 liter V6 from the 1990s that powered the 300ZX was only a 7.8:1 compression engine, and the V6 in the current Mustang is 10.5:1. Back in the 80s a 10.5:1 compression was only found in racing engines.
Also you have to remember the oil change interval. I doubt anyone running the old dino oil was driving 10,000 miles between oil changes for very long. An engine running modern synthetic oil will have less engine wear after 10,000 miles than an engine running dino oil will have after just 3,000 miles.

I don't know. I have a 4.6L and I don't have the 5.0 tick issue.
I use the M synth blend 5w-20 as recommended, and my engine has that nice mild clickity clack and whir of an OHC.
No resounding tick.
I change oil once/year per my driving (which is 3-5k/yr) right before winter storage. Which I'm going out to do right now.
I still wonder if the 5.0 tick issue is because the TiVCT uses 'cam torque action', rather than all hydraulic action like the 4.6 VCT. Perhaps that 'backlash' so to speak adds extra strain on the 5.0's valve train, creating the noise in a number of engines. Just a thought.

This actually is really good oil. I'm sure not as good as Mobil 1 and Royal Purple but for 17 bucks for 5 quarts full synthetic base III oil. Winner winner winner as well. Lmao
