Best Oil

[carps_accord]

if it wasnt for this website...i probably would never of used synthetic. But i read a section about the myths of syntec....syntec will not ruin your engine

i use castrol syntec, sometimes mobile 1.

I use mobil 1 full synthetic. But i read on evolutionm.net that mobil full synthetic isn't really a full synthtic oil anymore or wasn't gonna be. Not sure of the validity of this just something i read. I still use it in the evo and now in the cb7.

only true of mobile 1. For some reason...they use conventional oil base stock...add some stuff...then decide that magically makes is synthetic.

SOME mobile one is...but it's like made in germany? There's a write up in a thread here somewhere.

RP is synthetic...and from the looks of that test benjerman112 posted up, Valvoline's is synthetic too.

HOLY SHIT!!!

I'm using castrol synthetic right now...synthetic is the best, you save money and it protects better!! I gotta find some royal purple!!!

*I am at least switching to valvoline synthetic..

Thanks for that link!

dude when i saw this my mouth hit the floor! i thought mobil 1 was better than that.

Mobil 1 used to be an excellent oil. In recent years it seems they have let the quality of their base stock slide like said above, its not a true synthetic base oil. Royal Purple is alot of marketing hype and bs, and doesnt have an particularly great additive package compared to leading brands such as Mobil1.

hmmm...it still protects better on that bearing test...I think I'm gonna go with valvoline synthetic meeself

[starchland]

that bearing test means squat

that bearing test means squat

How's that? Granted it isn't definitive and it is only ONE test...and that one test says nothing of longterm life/protection...I'm sure you could make an oil that would perform great in that one test but still ruin an engine...but based on that one test I can say I will not be using mobile 1, and that either amsoil, rp, or valvoline syth will protect better.

You want to see what oil is best for your engine. Get a sample of your engine oil after running it for a few miles then send it in for an analysis. A lot of diesel people do this.

Mobil 1 non-synthetic. It's what I've always used on this new engine, and the first time I ran it, it seems like it picked a lot of gunk up on the first change. I've had a few changes since then, and it comes out very clean. I usually drain it after about 5,000, and it still has some color to it. I plan on going back to mobil 1 synthetic like I had with the last engine, which is why I've kept mobil 1 non-synthetic in here so far. Has treated me well.

Royal Purple for me....I noticed an immediate change in the way my engine preformed!

so has nobody has ever used castrol edge yet?

I just put it in last week wheen I changed my oil (Castrol EDGE). I've noticed that it is thinner on its consistency while pouring it in compared to Castrol Syntec. I have been using Castrol Syntec for at least 50-60k miles and never had a problem with it. Price wise the Castrol EDGE is about $8.00 for a quart, almost the same as Royal Purple. As far as performance gains, I haven't really drove the car as much yet to evaluate. I hope it is worth the $1.50 extra compared to it's Syntec predecessor.
