Re: What Type of Motor Oil?
Today's synthetic is a LOT different than early generations of synthetic.
Pointing this out, because if you are searching the internet or talking to some old grandpa regarding synthetic, then likely you will find old info stating not to go back and forth between the two.
Brand name quality synthetic is pretty much interchangeable with natural oil.
It's not 100% the same, but it's really close. Worth giving a shot if you are set on using synthetic.
check your oil level a few times and if you aren't loosing any of the synthetic then you are fine to use it.
I use Mobil 1 as well - 11X,XXX miles on current engine.

Re: What Type of Motor Oil?
Weather really does play into it.
Use the engine manufacturer recommendations for which oil to use and at what temp.
I live in the warm climate of So. Cal. and use 10/30 all year round just like the engine maintenance specs call out.
The closer you get to freezing temps, then the more difficult it becomes for the oil pump to push high viscosity oil through the motor *** especially during cold startup***!
At around 30degrees most manufacturers recommend changing to 5/30 or 0/30 oil.
You will have to look in the maintenance guide for your engine to see specifics.

Re: What Type of Motor Oil?
^^^ Eghhh? What's that sonny, could you speak up a little?
This is an age old question that's gets asked over and over. Do what your budget allows. Just remember one thing - just because the bottle may say to change it every 15k miles or something doesn't mean you don't have to check your oil or change the filters multiple times. All that hoopla talk about it lasting that long is extremely misleading. If you have ran standard oil this long there is no point in switching now. Sure the new fangled synthetic oil has some good properties but the build up around seals and wear on the engine is already there. Countless times have I seen people switch over only to have "mysterious" oil leaks develop...

Re: What Type of Motor Oil?
Synthetic oil doesn't break down (at a molecular level) like conventional oil - it is the additives in synthetic that break down. All oils pretty much have the same viscosity at operating temperature. So unless you are racing trucks accross the Sahara Desert, you should always use 5w/30 (or 0w/30 if you can find it) because it is more viscous at colder temperatures - startup, when your engine receives the most wear.
If you buy a new car or have your engine rebuilt, then you should definitely use a good synthetic cause it will cost you less money in the long run, on oil (changing it less), and your engine will last longer. There's a reason that valvoline's engine guarantee is 300k for synthetic and 150k for conventional (and yes, i know that it is just a way to suck you in to using their oil only - I dont use valvoline).

Re: What Type of Motor Oil?
I've switched from conventional to synthetic and back on multiple cars with no problems. Viscosity should be the same regardless of the type. As mentioned, the weather is more of a factor. You should use what is recommended for your engine, and go from there. My B16 says 10w30, but in the hot Georgia summers I run 10w40. For almost 20 years I've used Fram filters, though people will tell you not to. Just use reputable brand names and don't buy generic.
That said, I'm a big fan of castrol gtx.

Re: What Type of Motor Oil?
Check out this thread, on the second page I explain how Mobil 1 is no longer fully senthetic, and hasn't been for about 5 years. Test results and proof posted as well.

Re: What Type of Motor Oil?
I use Penzoil and Purolator filters most of the time. 10w-30. I switched to----Bram? No. That's not right. I can't even remember. Something high end because of the turbo. But you really don't need that. Mobile 1 10w-30 or 5w-30 if you live further north. Purolator filters are tried and true, plus cheap, for me personally.

Re: What Type of Motor Oil?
I recently switched my crx and wagon over to royal purple HPS 10-30 and WIX filters.
(The standard royal purple is without some of the good additives... intended for newer vehicles still on warranty or something.)
