i used to live near the royal purple facilities. the oil is crap compared to mobil 1 or redline and the price is close to that of redline. not worth it, although they make a great transfer-case oil, which i am sure you won’t needing. just my thought on royal purple. my dad used to run havoline, the texaco oil, and i use to see the different results of car engines with various oils. mobil 1 was and is still the best when it comes to synthetic, havoline was second until shell took over texaco and chevron is now holding havoline. which is also why chevron has an oil out. anyways, the best oils for the money are mobil 1, remember it has been around since 1968, the first synthetic oil. and castrol is second to it. redline is great if you want to spend the extra money. stick with mobil. i do have a question about break-in, if you rebuild a motor, should you do the same break-in as with a new motor, i.e. the first time at 250 miles and not going over 3000rpms the change at 500 miles and not revving more than 4000rpms, and finally doing a change at 1000 miles and not revving higher than 6000rpms. i know the revs will differ from car to car, due to gear ratio’s and the size of the engine. i averaged the break-in that we are doing on my mom’s E320 4matic(sold the TL) and my buddies Z06. which, coincidentally, both take mobil 1 syn. sorry this is so lengthy.
oh yeah, WIX filters are probably the best to get, you have to ask for them, most stores keep them behind the counter because they come in small shipments, they just don’t make as many. they use a better filtering technology and have a little bit better holding capacity. the newer fram filters are about the same as WIX filters from 3 years ago in terms of design.

Castrol maybe second, BUT unfortunately, they no longer market Group IV/V synthetics anymore in North America. Castrol Syntec is pure Group III that has been severely hydrocracked. If you want Castrol Synthetic, you’ll have to go to Europe to get them (they are marketed as Castrol SLX I think).

how about hamp filters, heard they are very well made, but a bit pricey
hamp filters are good too.
Here are my oil filter recommendations (not in any particular order):
- Mobil 1
- AMSOIL
- K&N
- Bosch Premium
- Purolator PremiumPlus and PureOne
- Wix
- UAP NAPA Silver and Gold (both are Wix filters)
- STP
- AC Delco
What I do have to warn you guys is, the most important filter of them all is the AIR FILTER! I rather see you guys using a Fram oil filter with a K&N or Foam Air filter rather than a high quality oil filter with a Paper Air filter.

Royal Purple
I use Royal Purple. I got a 1st B16. After I put it in, along with the platinum 4 spark plugs, I could feel the difference in the low end and the car felt smoother. Now I haven’t used the other synthetics so I don’t know if all synthetics are supposed to do it. I liked it though, kind of expensive though. I’ll try that Mobil 1 tri syn or supersyn (whichever is cheaper) and I could post an update. I doubt I’m going to use the platinum 4’s next time though, I heard they’re not good for my coil or something, so I don’t know how significant it is putting those in was.

Matt,
The SuperSyn is the reformulated version of Tri-Synth. Availability right now in Canada is non-existent, so I cannot tell you whether it will be more expensive. However, I am being told that it is a bit more expensive, but nothing outrageous. Tri-Synth. has more ZDDP additive package because API SJ allows it. Now, with API SL, Zinc and Phosphor content cannot contain more than 10%. This cap is only applicable to 30wt. oils. Heavier oils such as 40wt and 50wt have no limits and yet can still be API SL certified. It seems that Mobil addressed this lack of Anti-wear presence by improving the base stocks. So, retailers are pushing to eliminate Tri-Synth off their shelves.
As for testing, again, I strongly recommend an oil analysis rather than doing a “by-the-butt-dyno” test. It’s not really something tangible, especially when you start changing other things (ie. your spark plugs).

Oz
