I went through the break in and just gave it a new oil change but I put in 10w-30 instead of 5w-30. I live in Mass. so it's pretty cold here! Did I do anything wrong, or will it be ok?

Help!

Also-when should I start using synthetic?

10/30 is fine. that is what we used in the garage all the time and we are in maine. i would go synth. after 12k. just to let everything seat.

IMO synthetic isn't worth the trouble. You still have to change it. you're going longer with potentially dirty oil circulating in your engine. Why not just change good quality motor oil a bit more frequently? This way you've got clean oil running more of the time.

i don't run my mobil1 any longer than normal oil. i don't think people should run it like 5k or anything like that. i go about 3000-3500. it made a big difference in my engine (4g63) by taking away a lifter tick. and it doesn't break down as quickly as regular, so even though it looks like pooop when it comes out after 3500, it still protecting the engine the way it should. go to wal mart and a 5 qt. jug is only like $18. worth it imo.

Did you change it at 1,000 or 3,000? I'm at 1,400 and I thought I need to wait until 3000 for the first oil change is this right?

Thanks

well the idea behind using normal oil first is to let the many seals in the engine get conditioned. seals leak two times, when they are brand new, and when they are old. however, if they leak when they are new, they will usually stop once they properly seated. its pretty much just a precaution to use reg. oil and wait for synth. but i wouldn't worry about it. i am sure nothing will happen b/c it had mobil1 at 3500.
