I just picked up 1L of Castro 10w-40 for my bike and it was like 10 bucks. I'm Wondering if there's another type of oil that is just as good for a 450 four stroke but half the price. Thanks.

Lots of threads already on this subject... 

 

Everyone has their favorite oil, probably every reply you get on this subject will be different.

 

Also, to advise on a brand it helps to know where you are located...  since you mention buying a liter

of Castrol we can suspect that you are not in USA but that doesn't narrow it down much...

 

For my WRs I use 15w40 diesel oil.   Price is right at around $10-15 per gallon , readily available, and

is heavy duty without the friction modifiers found in automotive oil that may or may not damage your clutch.

 

1000s of miles on this oil in harsh climates and it works great.  I am happy with it.   Someone else will

have a different favorite...

Rotella T6 - 5w-40. Walmart $21.50 for a gallon. Hard to beat that for full synthetic.

How much money are you trying to save?  Its only a qt of oil... not 100 gallons!

+1 On the Shell Rotella Full Synthetic endorsement. It is 5w40 and as an earlier poster said, costs less than 22 bucks a gallon at W-M.

 

I've used it for many years in street bikes as well as dirt bikes.

 

I know it is intended to be used in diesel truck engines, but it actually meets or exceeds all the JASO standards that Japanese motorcycle manufacturers require. 

 

Here are a couple of articles that lay out the pros and cons of using oil formulated for motorcycle use vs. automotive oil:

I'm thinking of switching to synthetic oil after reading that page. I was running 10w 30 last year and was wondering if switching to synthetic Could be bad for for my bike ? Thanks for the opinions guys.

If I can get 2 for the price if one than I'm going to do it. Common sense if you ask me
