so here's the story. coming up soon on a oil change. nearest honda dealer is 4hrs away. local shops, have no stock on 10w-30 oil. they do have amble 10w-40 oil.

so my question, can we use 10w-40 oil in these bikes? any recommended brand? regular motorcycle oil or synthetic?

i got two bottles of castrel 10w-40, it was on sale for dirt cheap and always had good luck with castrel on all my vehicle but would really like to know for sure before I go ahead and do anything. any input be great. thanks in advance.

You don't have a new member statement about what your bike is so I don't know if it is the thumper or the twin.

Can you not find Shell Rotella T-5 10W30 in Fort McMurray? WalMart ships that stuff to stores if ordered. Here's my order (shipping was free):

Rotella 10W-30 T5 Motor Oil, 2.5 gal 1 $40.77 $40.77


This is used in a 471 cc twin. I have also used Castrol 10W-40 in the bike, but the oil pressure at idle is so low (13 psi) that I really didn't want to use a higher viscosity oil. I currently have 15K miles on the bike and needed to adjust the shims recently (ahead of schedule; all 8 shims needed to be downsized 0.05 mm (two size drop)). I am a "maintenance nut", changing oil and filter every 3000 miles. YMMV

Well use the 10W-40 but consider an early change again. I don't have a Service Manual for the 286 cc engine, so I can't check the oil pressure, but, I will bet that it is similar. I was worried about getting good top end lubrication with higher viscosity oils. That was never a problem with the old air-cooled stuff (much bigger tolerances) but the modern water-cooled engines run very tight specs and prolonged use of higher than spec viscosity oil might cause a problem. Why take a chance? Have them order it in with their regular shipments.

The Rotella will not have energy conserving additives. Standard automotive oils will have have those additives. I do not think that moly is used anymore, but that was the bugaboo 25 years ago; moly can lead to clutch failures for bikes like ours, where the engine and transmission share the same oil.

He probably has Castrol GTX 10W-40 which has no energy conserving additives. I have used it in all of my older motorcycles and the '99 Miata.

I looked around a bit at synthetic, but couldn't find any 10w30 that listed all the specs that were needed... so just played it safe and ordered what the manual said to use.

Plus, the oil I drained at 575 miles still looked brand new, so it seems to do the job.

From what I could find, it seems that the engine oil is also for the transmission and clutch which means regular automotive engine oils won't meet the requirements. The Honda motorcycle oil apparently contains additives for the clutch/trans so has a different spec.Here's a pic of the page from Honda's manual:

Chose this:

Maxima (30-019128) Pro Plus+ 10W-30 Synthetic Motorcycle Engine Oil - 1 Gallon Jug

For first oil change after breaking, very pleased with the improved performance. Full synthetic with esters, engineered for wet clutch motorcycles
