First time with synthetic

[Shane55113]

i would never keep any oil in the car for more then 5k, its better to have clean oil then dirty oil, becides that how long do you think that filter will last? not 15k

[HiImBrian]

Yea I change the filter. I've never had a problem before.

Ams oil FTW in my dsm. They say it last up to 30K! I change it every 15K though just to be sure:)
Just keep in mind that oil comes from Superior, WI....if you've ever been there you'd know why this is a bad thing :) If you are going to be running a change of oil for 15k miles you really should periodically send it a sample to Blackstone Labs for an oil analysis so you know how its holding up.

Syntec is a cracked synthetic, so it is not a true synthetic, it is still much better than a regular oil. I always used it until they changed. M1 is a true synthetic, but my DSM's never seem to like M1. I use valvoline synthetic now. Now that it is broke in, it will probably get redline or royal purple in it.

at first i thought that this thread was going to be dumb, but it has a lot of info that i did not know. Thank you to all that contributed.
I was using M1 syn. and changing it every 3k like regular oil. I usually a Wix filter also, that i get from napa.

Changing M1 oil at 3k miles is WAY overkill and is just wasting your money and time for no good reason. At the very least, I would wait until 5k to change out synthetic.

JET, I would stay away from Royal Purple fluids if I were you; their beginning protection is OK (by no means better than Redline, M1, Amsoil, etc.) but their aditive package is not very durable at all and wears out quite quickly. If you can stomach the price, its pretty tough to beat Redline engine oil. Actually, with the exception of 75W-90 gear oil, everything Redline makes is great quality.

Just curious where you get your info about the Royal Purple not being very good for the long term? I am not doubting you, just curious where you heard this.

Damn, I've been changing with synthetic every 2,500 - 3,000 miles for years. Think of all the money!

Oh well, I probably will continue to change it like that. I just always look at my car and think "She looks like she could use an oil change" :)

Reading way too many UOA's from Blackstone Labs and and reading technical statements and discussions from oil chemists (whatever they are called).

I also use Rotella-T. I may change to mitsu filters now though.

Good find on the cheap oil Andrew!
