I think you would be ok switching to synthetic at 1k, but 3k is fine too. I doubt it take that many miles for the rings to seat.
bbomar said:Hudson, I would use Mobil1 0-40. I think you will like the results.
Comes recommended by several people on here.
Really? I found it at Walmart!!HudsonValleyTitan said:Yes I've used that before. Problem is...it's not easy to find so I just went back to the 5W/30.
I'm no expert by any means but all thats contrary to everything I've ever read. And I'm not sure, being that that came from the Mobil company, that I believe them. I was always told that dino oil is needed to properly seat and break certain parts in. What I think they're not telling you about those cars sold with synthetics from the factory is that unlike regular bench testing, they're bench broken in first. If anyone knows for sure that's wrong, please show us.TYTAIN said:Several manufactures put syn in straight from the factory. No break in needed.
From Mobil 1 website
Myth: You should break in your engine with conventional oil, then switch to a synthetic oil like Mobil 1
Reality: You can start using Mobil 1® in new vehicles at any time, even in brand new vehicles. In fact, Mobil 1 is original equipment (it is installed at the factory) in:

One of the myths surrounding synthetic oils is that new engines require a break-in period with conventional oil. The fact is, current engine manufacturing technology does not require this break-in period. As indicated by the decisions of the engineers who design the high-performance cars listed above, Mobil 1 can be used starting the day you drive the car off the showroom floor.
My dealer gives free oil changes for the life of vehicle ownership. They dont use synthetic, however. They use regular Mobile 5-30. However, if I want the synthetic, I can buy it wherever I want, bring it in to them, and they will provide the Nissan filter and put the synthetic oil in for free.GoFast33 said:Hey HVT, did they give you the first oil change for free (in addition to your free hat)? I got the free oil change, but not the hat. Wonder if I can get them use Mobil 1 (at add'l cost, prolly)? This may be a newbie question but what exactly are the benefits of using synthetic? Longer engine life, longer interval between oil changes (how long?), better performance, better fuel mileage? Inquiring minds (and stupid people like me) want to know!
Me too - that's why I'm still on dino juice...SemperFiTitan said:My dealer gives free oil changes for the life of vehicle ownership. They dont use synthetic, however. They use regular Mobile 5-30.

In other words, its a free oil change for life, except for synthetic oil if I choose to go that route.
An engine will break in with synthetic or regular oil. Most people think that synthetic oil is not crude based. This is not true. Even synthetic oil is formulated from crude base stock. Its the refinement process and the additives/detergents that make it a "synthetic oil".HudsonValleyTitan said:I'm no expert by any means but all thats contrary to everything I've ever read.

As for finding the 0-40 Mobil1 one, I'm never about to find anything at out superWalmart other than the 5W/30 or 10W/30. I'll kep my eyes open but I think I'm leaning toward a dino chnage at 1k and a swap to synthetic at about 5k.
My dealer only offers the first oil change for free but a lifetime powertrain warranty if the work is done there. They also offer a mobil 1 synthetic oil change.SemperFiTitan said:My dealer gives free oil changes for the life of vehicle ownership. They dont use synthetic, however. They use regular Mobile 5-30.
