Well I used to use M1 in everything and I believe it is a great oil. My problem is that I can't go 10,000 miles before changing the oil. M1 and full synthetics give you a great advantage if you are comfortable running those intervals. Personally I only like to go around 5-6k between changes and believe full synthetic will provide no more protection during that change interval. In my opinion a synthetic blend gives me the best of both worlds and is what I have started using. BITOGers def love Pennzoil and I have been impressed with it so far.
Each brand has a product line that is comparable to other brands,so "better" is tough to say. I hate M1 however ill use it if the price is right. I'm a pennzoil fan.
M1 line is basically equal to pennzoil platinum/Quaker State Ultimate Durability. Mobil 1 Extended Performance is equal to pennzoil ultra basically,then of course there is the conventionals.
Buy whatever is the best deal at the time. Conventionals are good for 5000 miles or so. Synthetics are good for 10000 miles. The EP and ultra lines are 15000 mile oils.
And as said above there is no gain by running synthetics for short intervals. They last longer in service,they don't protect better,they protect longer.
