The Mobil 1 plot thickens!
This is Mobil's official response to an e-mail I sent them a few weeks ago. I was asking for clarification on when they recommend the introduction of their synthetic oil into a new engine. Enjoy!
Thank you for contacting Mobil.
You can start using Mobil 1 in new vehicles at any time. In fact, Mobil 1 is the factory fill in Corvette LS1, LT-1 and LT-5 engines. And Mobil and Porsche just announced a new partnership that will also have all Porsche cars manufactured at the Zuffenhausen plant lubricated with Mobil 1. 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 the decisions by the engineers who design the Corvette and Porsche engines indicate, Mobil 1 can be used in an engine from the day you drive the car off the show room floor.
If you have any additional questions, you may contact us at our E-mail address: lubes@ffx.mobil.com or by phone at 1-800-ASKMOBIL.

Should I wait to put Mobil 1 in a brand new engine. Some people say that I should wait until after the break-in period. Others put it in as soon as possible. What do you recommend?

I would still "break in" your engine on regular oil. I wouldn't think that you need 10,000 miles or anything, I would rather think that after 3,000 miles or so your engine has seated the rings and the like. Take it easy for whatever miles the owners manual recommends, then gradually get more agressive with it.
When (still waiting) my truck gets in I'll change the oil at about 250 miles (as soon as I get home from the dealership), again at 1,000 miles, and probably at 3,000 start using Mobil 1.

Mobil is correct. An engine with today's moly based rings does not take 3000 miles to seat. A motor today takes about 100 miles to seat the rings fully. After that you can immediately switch to synthetic.
Good info from Mobil and it sounds reasonable. Has anyone asked Ford what they reccommend for break-in for the Tritons? Does Ford fill OEM any of their engines with Mobil 1 or other synthetic? – SDDL-UP, I'm still waiting for a truck too.

The 2000 ( and 1998)owners manual states that there are no break in period rules for the F-150 on page 2):
" There are no particular breaking-in rules for your vehicle. During the first 1,600 km (1,000 miles) of driving, vary speeds frequently. This is necessary to give the moving parts a chance to break in.
If possible, you should avoid full use of the brakes for the first 1,600 km (1,000 miles)."
At most, I would wait 1,000 miles to switch over to Synthetic oil. No reason to wait until 5,000 or 15,000 miles. Remember, many manufacturers ship vehicles with Synthetic already in the engines. I would bet that more would, if the oil was much cheaper.
I just changed over to Castrol Syntec Synthetic oil last night at 667 miles.

Sounds reasonable. The trouble I had was with an '87. Things change.
