Anyone using Castrol 4 stroke motorcycle oil?

There's gonna be a ton of opinions on this one, so here's
mine. With an older bike I like using a good quality semi-synthetic
oil. Specifically I use Bel-Ray 20w-50 semi-synthetic, it runs cooler
and holds up better. Just make sure it is made for cycles, having
a wet clutch makes a difference. Brian
 
Castrol bike oil should be fine. There are various sorts, but all should be ok.
 
Castrol.....Good stuff !!

Castrol.....Good stuff !!

I've used Castrol GTX 20w- 50 regular automotive oil type for 15 years. I have had 0 trouble at 72,565 miles..............Chilly.
 
There's a difference between regular automotive oil and synthetic automotive oil. The latter contains anti-friction additives that don't work
with your clutch. That's why they make transmission fluid, or in this case
oil made for wet clutches (motorcycles). Brian

I've never used anything but regular automotive oil in any of my 4-stroke bikes, never a problem. Alway use B&M Trick Shift in the transmissions of my 2-strokes (runs cooler).
 
See if you can a copy of the motorcycle consumer news oil test from a few years ago....you won`t use auto oil with the star burst symbol again. Oil that you used for the last 15 years has been changed due to EPA regulations....I used kendall GT 1...loved it but I sure don`t run it now.

Me too!! No Problems at all!! My clutch problems are un-related to the oil, just wear and tear!! :lol:
 
The oil article is great. It looks like the filter article was written sbout auto spin on types. I only say this because the fram filter shown does look trashey. The fram that i have been using in my gs1100 looks exactly like the filter that suzuki sells us and comes with a rubber gasket also.
 
I think the fram filters like we use in the GS series are fine....they do not have a check valve in them(part #6018) as used in most modern suzuki`s so I stay away from thier spin on filters. I usually order my filters and use the hiflow brand. Made in europe and to oem specs. On the suzuki spin on filter even the filter wrench works and have the check valve(btw the check valve is to hold pressure in the filter so you do not get a vacum in your oil system every time you fire your bike up). I also use them in every bike I own...much cheaper than fram. 8)
 
There is a much later oil test done by Don Smith probably 2 years ago. Since this 1994 article the auto oils have been changed. It also was in motorcycle consumer news. I will mail him and see if I can get the article.
 
I use Fram filters in my 2V 1000S.
They come with the gasket. I usually buy a couple at a time.
I get them for about $4 US.

I use Castrol 10W-40 in the spring then 20W-50 in summer.
I also have an oil cooler.
No problems. I have a Barnett clutch that's still holding up after about 10K
on it. It only slips when I make it slip.
