Synthetic Engine Oil preferences?

[hootmon]

Amsoil states double the recommended interval or one year...
On a Magna the book says 7000 miles and that's for dino oil....
I usually run 8-9k in a year...
I change my oil once a year, usually in May/June just before the hot season...
I usually go with 20w50, but 10w40 is fine... 50 will cling longer, but 40 will flow easier... I go with 50 because it is also transmission oil and gear oil is usually 80 or 90.... That's my thinking, but it can be argued either way...

I thought I might weigh in on the oil topic.  I used the Honda Pro oils when the bike was new and changed oil and filter every 4k.  After much research, at 23k miles decided to use plain old Castrol 10w-40 in the winter and 20W-50 in the summer.  At 65k miles started changing oil and filter at 3k miles.  At this time I have 165k miles and the bike is still running good.  Its not using or burning oil.  I knew I was going to put a lot of miles on the bike and needed it to last since I commute 300 miles each week.  I know I have paid alot of money on oil and filters, but its like they say "pay me now or pay me later."

165,000 and counting, way to go Mike!


I have seen the same as Hoot mentioned above, synthetics you double your change intervals.

I use the heavy duty diesel oils in my bikes and go 10k between changes, in the cars I use the specific Mobil 15K guarantee synthetic and go 15K between changes.

I've had lots of luck with Maxima Maxum4 Full Synthetic 15w50 oil. Temps stay cool and shift and clutch are great. I've been very happy with this brand. It's reasonably priced at $55 plus shipping for a gallon. Also, I've never heard anyone complain about it and lots of guys on the pro racing circuit use it. Just my 2 cents.

Hey dude, you still hanging out overseas?

Nope. Been back in the US for almost a year (Keller, Texas). Had trouble bringing my bike back, though. US Customs said I couldn't bring it or register it because the frame number was not from a US bike (Japanese frame number). So, I had to take it apart just before the move and had everything but the frame shipped to the US (Customs would allow that... go figure). Had lots of other stuff to deal with getting settled in, etc. and the bike got put on the back burner. I finally bought a local Magna (in November) and I plan to start tearing it down to the frame and sell off all the bits and pieces from it. Once that's done, I'm going to make all the modifications to that frame, powder coat it, and then put my bike back together on that frame.

I think I'm going to have to try and organize a wrench session at my place to take the bike apart and another one to put it back together. If the free pizza and beer isn't enough to get people interested, maybe getting a closer look at what's involved in the CBR wheel swap and VFR engine swap will.
