Is “High Mileage” Motor Oil Safe?

[yamahaSHO]

Ok this makes no sense. Why would one purposely choose an oil that was "lesser" than another? Oil is cheap, just put the best in that crankcase you can. Does anyone ever say "Well I'm gonna drive slow and easy for the next 5k miles so I'll just put some dollar store oil in this time."

Some oils are better at X and some at Y... It doesn't mean you're using a "lesser oil".

It makes perfect sense. You just have to stop thinking there is a "best oil". There is a best oil for your usage.

Do you think a Hoosier R7 should be run in the snow? It is the best tire... At something. Not snow or cold though.

I don't always use "high mileage" Mobil 1...Mobil 1 in general every 5K or less is what's important...

So I’m not trying to pick at you, believe it or not, but give me a real world example using our 2.3 ecoboost Rangers; Let’s say I’m a bearded bro in SoCal and I’m a desert runner and jumping whoops five days a week and have 20K in mods on my truck. Verses I’m an old man in BFE Ohio, who drives trash to the dump twice a month at 40 mph and have 3 old blankets covering my seats. What are some Real examples of different oils that these two users would NEED? And why the heck could they not BOTH put Mobil 1 5W-30 and be just fine?

First off, Mobil 1 5w30 is a resource conserving oil and will shear to a 20 weight pretty quickly. However, in the most basic explanation of your example, one vehicle needs an oil with high shear strength and be able to withstand significantly more heat. The other vehicle doesn't have the requirement and may be protected perfectly fine with an oil makeup that isn't an actual synthetic base stock (yep, "full synthetic" isn't what you think it is), doesn't need to be the same weight, and may not benefit from additives that the other usage can protect against.

Value amount in 'mods' mean nothing.

I think you should do research at this point. There is more that goes into a proper oil selection (think race teams... At least, understand what they are trying to accomplish with any given oil), but the information and testing is out there.

Indeed full synthetic may not be what you think it is. Castrol "Synthetic" cannot be sold in Europe labeled " full synthetic" because in their view technically it isn't, as it is based on hydrocracked mineral oil. This doesn't mean that it isn't a good oil, but rather it's made by breaking down and then rebuilding mineral oil to more uniform length carbon chains. Castrol won a court case to call this oil synthetic in the US.
Whereas for example Shell make synthetic oil by building it up from methane gas (CH-4) molecules.

Interestingly most companies in Australia market hydrocracked base oil as "semi synthetic" even though Castrol is sold here as "synthetic"

No I simply asked you for real world brands/weights/examples of what You (as a self proclaimed expert who attended a class on the subject) would run in a 2.3 living those 2 different lives.

I never said I was an expert, but I'm not naive on the subject. The reason of pointing out the class seems to have gotten the wrong, or no point across to you. The point was that the subject of oil selection based on usage/requirements is a real thing, so much that a class was offered and hosted by engineers that do this every day, at the biggest racing trade show in the world. This sort of knowledge is actually really beneficial for me as I use engines a bit harder than most. There is no "best oil", there is selecting an appropriate oil for your requirements/usage.

Take the time to understand or not... Makes zero difference to me. You've been provided some insight to get you pointed in the right direction, now you can research it and get a better understanding, but I don't feel like I owe you anything more.

So..all that cool talk and not even 1 or 2 examples of oils hip enough to use?

I actually gave you an example, it just may not be the spoon feeding you're after.

Well you actually did not give any examples at any time that I can see, just a lot of academic buzz talk, but hey you sound cool bro.
