Re the above link...

Of course I would expect to see the following on the AMSOIL Site:


Question: Can AMSOIL motor oils be mixed with other brands?

Answer: Yes. AMSOIL synthetic motor oils are compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil’s life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Mixing other oils with AMSOIL motor oils may also void the AMSOIL limited warranty.


The preceding quote is also biased and self-serving and does not constitute as impartial documentation concerning any adverse affects of mixing brands...I'm still waiting for that. Besides, I doubt that any CB owner on this forum leaves the oil in his bike for any extended period of time....surely not long enough for any "mixed-oil" issues (if there are any) to ever arise. For the brief time that the oil is in our bikes, you could probably even get away with using (dare I say it?) Quaker State (if they made an approved, wet-clutch, motorcycle oil)

Quaker State (if they made an approved, wet-clutch, motorcycle oil) It'd be near impossible to attribute any lubrication-based failure to oil mixing. It'd take an insane amount of control. For that reason you'll probably never find any documentation on the issue. For the sake of discussion, think about how often oil gets mixed when you switch brands on a normal oil change.

I probably should have worded my statement differently. It's good practice to not try to mix your oils. You can't really lose by making sure whatever fluid in your engine isn't causing any undesired reaction or performance.

Agreed!

How about this- I've been thinking. Yes, scary thought, but regardless of that.....indulge me...

Now think for a moment how many morons there are in this world. Some of them are motorcycle owners. ( Not present company of course) And how many bikes have we seen advertised that have been stored for years? And how many people rarely change the oil? I'd say a lot. Now ask yourself how many engines have you heard of grenading from an oil issue?

I'm going to be a negative Nancy and say me oils become acidic over time and will start to corrode materials. I've seen a handful of guys ride bikes right out of storage for several years and lose compression. But that's the fault of storage, not the oil.

If they do make it, then that's the definitive reason to use it.
They can formulate it and tweak it to whatever is best for their engines.

Hm, but they also could tell their needs to an oil producer, who knows better, how to do it. Being a good engine manufacturer does not necessarily involve, being a good oil producer.

Btw, I'm thinking about to use `Castrol Power1 Racing 4T 10W-30'.

I completely agree with you. The oils do degrade over time, and become acidic. And yes, the main problem I have seen and heard with old bikes that have been in storage, is low compression. Most of the 35, 40 year old CBs I see offered for sale have between 5,000 and 25,000 miles on them, certainly not enough to get worn out.

What I'm thinking is that even 40 year old bikes that are ridden with old and maybe worn out oil for a while still are OK with an oil change and some minor care. That old oil maybe will start a harmful process and will hurt the engine in the very long run, but it doesn't destroy the engine in anyone's lifetime. So IMO, these endless discussions on what to use and what not to use for our 2,000 mile change intervals is largely a waste of time. (Not meaning to insult anyone, I discuss oils too)

Dale Walksler at Wheels Thru Time told me bikes are inanimate objects and don't know if they were shut off 70 years ago or yesterday. He will take an old Indian that hasn't run in 60 years, heat the oil in the crankcase with a torch to warm it up and thin it, put some fresh gas in it and fire it up and take it for a spin. I'm sure he does a complete service after that but he's certainly not past running an engine with very, very old oil in it at least for a few miles.

Boom! Exactly! And, if I may, I'd like to carry another point home. Honda branded oils MAY NOT be the best oil for your bike. Perform UOAs. Environment, riding habits, and other external factors will dictate the best oil for your application.

If you are using Honda oil or any other name brand oil, you're fine.

If your intervals are longer than what Honda prescribes for your engine, proceed with caution.

[NightRider_imp]

Me? After all this discussion, you guys have sold me on Honda not knowing the best oil for their bikes. I mean, they are in the business of selling bikes, right? So knowing pure STP is as slick as it gets, I put pure STP oil additive in after removing the Honda crap oil. It took 14 little plastic bottles of the stuff and an hour to pour it in, you know, cause it is so thick. THen I heated up my oil pan with my daughter's best hair dryer (while she was out) and turned her over. Purrs like a kitten. Compression at the rings is easily double resulting in 28 percent increased horse power and naturally wear is zero. So, I have to say pure STP oil additive instead of oil is the way to go and Honda should package it as Honda oil from now on. Those Honda engineers obviously know less than I do...

[Lord Popgun]

Back in the day my brother told me he pulled pans off cars that used STP and it was all in the pan. Does that sound like a real thing?

And to stay on topic, I use Honda oil. Am I a bad person?
