Mobil1 has their own website www.mobil1.com and i can't get it to link properly here but they state you can use their oil at anytime and it will not effect break-in. Here's a quote:


MYTH: You should break in your engine with conventional oil, then switch to Mobil 1.
FACT: You can start using Mobil 1 with SuperSyn™ in new vehicles at any time, even in brand-new vehicles. In fact, Mobil 1 with SuperSyn™ is original equipment (it is installed at the factory) in:


Chevrolet Corvette
All Porsche vehicles
Mercedes-Benz AMG vehicles
Dodge Viper
Ford Mustang Cobra R
All Aston Martin cars

One of the myths that persists about Mobil 1 is that new engines require a break-in period with conventional oil. Current engine manufacturing technology does not require this break-in period. As indicated by the decisions of the engineers who design these high-performance cars, Mobil 1 with SuperSyn™ can be used in an engine from the day you drive the car off the showroom floor.

Interesting...finally some facts.

I waited until 7500 miles to switch to Amsoil from dino oil. I also picked up 1+ mpg average improvement after doing so.

From past experience in a couple cars I have owned in the past including an 86 and an 88 sentra you can switch from conventional to synthetic and even mix them it's no problem. There are even hybrid oils out there that are mixed already but that seems like a waste. I did notice that if you go to synthetic later on in a cars life like 100K+ miles the synthetics can get past gaskets a little easier, but i was still using no more than a quart every thousand miles in a car with 140,000 miles.
