Oh, I use Mobil 1 15w50 with some SDDP additive from Eastwood...

Synthetics!  Heresy!  Off with his head!   ;)

Huh?  I use AMSOIL 20W-50 V-Twin motorcycle oil in both of my bikes, and my acne cleared up!

"...and my acne cleared up."  

Now that's funny!

Most excellent, but did your marriage tackle grow as promised? [smiley=ROTFLMAO.gif]

I have some Amsoil to put in the RTP at next OC and I just put some of Gumby's snake-oil in the Dawg since it does boast about ZDDP on the back label.  It was only about a quarter more than the Castrol GTX and I don't have to put $5 worth of ZDDP additive in it so it's actually a bunch cheaper in my case.  But, paying over $5.50/qt for conventional oil still burns by a$$!

I really really want to use Specto Golden 20W50.  But the expense of it is just amazing plus it is hard to get.   :(

I'm using Castrol Edge Sport 25-50....made for high performance V8's.  Not a winter oil,but our winters are pretty mild compared to other countries...I just don't ride below 10C.

You want the ones that are round when they go in and round when they come out!

I tried the Wix Bendy filter and it didn't go in far enough for me to be comfortable with it.  So I took it out and measured it and it was longer by about an 1/8"!  So I'm sticking with the BMVV Bendy filter kit.

I have a new bendy filter on the shelf that didn't fit for the same reason. Can't remember the make. Might use it one day if can sort some shorter end rubbers.

I won't attempt to use a filter that's too long as I believe excessive compression can kink the pleats particularly on the straight filters and that can lead to a collapsed filter.

I've used nothing but OEM filters on the BMW bikes since new .

Personally, after seeing what kind of oil pressures these bikes have when cold, I am staying with the flex/bendable/hinged filters .

I run mine on the cheapest 'classic' or 'old car' oil I can find.  I usually find it at the supermarket.

I do however draw a line to 'reconstituted oil'...You have got to draw the line somewhere.

Its only in there for a short time (normal servicing intervals or 1 year).

And you have a filter.....

Synthetic is far too expensive and you will not be able to take advantage of any if its benefits.  Its an aircooled motor built to the 'loose' aircooled tolerances.  

This means that you will get contaminants in the oil very quickly and that it why the service intervals are short - or at least the oil changes are short - filter every other change.

Synthetics are for watercooled engines built to tighter tolerances.  The oil stays 'cleaner' for longer.  Which means that it can stay in the engine for longer.......Very simplistic explanation.

Synthetic oil won't make your airhead go any faster or put you at the front of the queue at the Pearly Gates when the time comes. ;)  i.e. you are not more worthy than me >:(

Barry had a good post about what to look for in oil.

It's not all about ZDDP... that is a lubrication of last resort.  An oil with a higher High Temperature/High Shear does not lose its film on important parts (like tappets) as easily as an oil with a lower HTHS.  Synthetics tend to have a much higher HTHS, so they can get away with less ZDDP

He made an example of Pump Deuce Diesels from VW, which use the cam to not only open valves but also control the injectors.  If they don't get the best juice, you're looking at a new camshaft.  And guess what...  the VW spec oils aren't just your grandpa's oil with a lot of extra zinc.

That said... go look at the data sheets from the manufacturers.  It will really help you pick an appropriate oil.  Just about anything these days is better than what the bike would have gotten 30 years ago.

Also... I think Snowbum has stopped encouraging Rotella-T in high speed engines.

I use Kendal GT-1 20w50 conventional motor oil.  $3 a quart, a good amount of zinc, and the HTHS exceeds the minimum requirements for the API service (i think it's 3.7cP)

Straight Dyno oil is getting hard to come by in the supermarkets.

Might have to start using semi-synthetic ::)
