When to go to synthetic??

There seems to be a few different opinions o when to do this, I have been told let the rings seat then go to syth.

I changed my oil at 2200, and was planning to go to sythetic @ 3750 when they suggest the first oil change.

Anyone think this is a bad idea?

Thanks

I would wait until 8k miles, then go to Redline 10W40, as long as the dino oil rating is the same as it is for WRX...

3000 Miles. Synthetic does not hamper break-in. The stock oil is plain old 5W-30. This is just MHO. I only drive 600 miles a month and 6000 miles will come mid winter. I only use synthetic in the winter.

I switched at 1K right after break in and no problems thus far....actually the synthetic seems more slippery and the engine revs more freely and spools a little quicker.....

I switched at about 2500 to synthetic and had no problems. Service manager at the dealer recommended synthetic.

Well it's not that they don't know anything this topic is more of a theory than fact and the theory is when are the rings actually set. More people that are cautious lean towards giving the engine more time to "break in" (set the rings)

Here is what I have found, these newer engine materials have a much faster break in period than older engines, the recomondation is 1000 miles in the manual that you refrain from hard acceleration, cruiseing at the same engine speed for long periods of time and what not. Honestly, after the first few hard accelerations the rings are set.

I am going to Synth for my next oil change which is 3750. I changed it at 2000.

There is my $0.02

The service manager also told me that mobile one synthetic is better than royal purple. He said that they observed engines with royal purple and there's more wear. The dealer also sells both types of oil so I think it was his honest opinion.

I changed mine to Mobil 1 at 1k. At next change, 5k, I will also be doing the gear box and dif with NEO and the break system with Motul. I've been running Mobil 1 in all my cars since my 1st one in 87 and have never had a problem. Almost all race teams run synthetic and they run most every race on a new engine.

Okay everybody, this old fairy tale about waiting 1K, 3k, 5K, ect to switch to synthetic has to end! Corvettes and Porsches come with mobile one from the factory, day one, mile one. heres a bit of info from the mobile one site http://www.mobil1.com/index.jsp

MYTH:
You should break in your engine with conventional oil, then switch to Mobil 1.

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.

yes, I know its from thier own site, but the fact remains that these cars do indeed come with synth from the factory.
