I've had my truck for 18 years and ran Mobil 1 Synthetic since the first oil change. 300k miles later, I walk into Autozone for oil and am confronted with Mobil 1 Normal, High Mileage, Truck and SUV, and Extended Performance. I did not see the normal stuff at first, but got it, and will keep using it.

Their site has so many oils:

They also have High Mileage Extended Performance, which I guess is both of the above, fuel economy, hybrid, ESP, European, Supercar, Classic Car (which I think means with zinc, we might like that), Porsche GT, turbodiesel, racing, motorcycle racing, harleys, super synthetic, super synthetic Euro, Full Synthetic (which is odd because I thought they all were), and full synthetic high mileage.

This is too many choices for me.

 

I'm guessing a lot of them were something like 0-20 weight as well!

 

Yeah, I am getting sick of the barrage of oil types. So many different weights, high mileage, fuel economy, multiple levels of synthetic. I am switching to Vavoline Restore and Protect. I will keep a two jug of all 3 grades on the shelf at all times, 0W20 Winter in the Challenger, 5W20 Summer Challenger and 5W30 for my Dakota and Olds. I have two cases of the VR1 10W30 synthetic. I will use a full case when I first fire the new roller cam this Winter. The last case will be the final quart in the next 6 oil changes with the Olds 358, mixed with 5W30 Restore and Protect. Heck the 5W30 Restore and Protect will probably do fine in the boat as well.
