After a few oil changes I made the switch to full synthetic. I was using Motorcraft semi syn and motorcraft filter.
After changing it seems like my ride is smoother...it's probably just a placebo effect. Anyone else notice anything from switching to full synthetic oil?

I've had full synthetic since my first oil change at just a hair over 1k miles. I think it runs pretty much the same as before but I have a better piece of mind that I have synth in there. Could be placebo, lol. Not sure.

My first oil change at 3k miles I used full synthetic and I thought too that it felt like a smoother ride. However, today I had my second oil change at 8.9k miles done by the dealer and they used the synthetic blend. I did not notice a difference going back to the semi synthetic...so I'm thinking it's a placebo effect.

I ALWAYS notice the engine feels smoother right after an oil change.
This car and my last car.

smoother quieter and better on gas 00 focus z-tech 249k miles last 4 oil changes with full synthetic, trips ranging for 780 miles to 1200 miles non stop trips.

I immediately notice a 20 HP gain after changing my oil with full synthetic. Washing the car seems to add HP and make it go faster too for some reason. Next year I might even splurge on a K&N CAI for that extra 500 HP.
Seriously man, it's all in your head. [;)]

the main reason to use synthetics is to extend time between oil changes. the oil will suffer less breakdown and probubly keep your engine cleaner internally. that might add up to a longer lived engine. i run mobile 1 in my vehicals and intend on continuing the practice.

I only use Royal Purple. I feel like it runs better but it might be a placebo [hihi]

It sure helps in the cold of the Canadian winter :)

I've run M1 in all my cars for over 20 years and the biggest benefit is obviously the change intervals but with any hard driven vehicle synthetics maintain a better temperature consistency and resists burning or "coking" (on a turbo application) and still flows nicely at sub zero temps at engine start up. I've never noticed a different from my butt-o-meter but it's peace of mind that makes me feel better.
