In my experience, the most significant oil-related failure is letting the oil level get too low.The biggest oil-related failures I've ever seen were from changing from one type of oil.

I'll have to check out Rock Auto. I buy most auto parts from them and never thought to buy oil there too.last time I bought oil for my truck I got it from Rockauto. It was cheaper per-quart to buy 6 single quarts vs a larger container. Seems pretty stupid to me, and its a whole lot less convenient for disposal too.
Motorcraft and other OEM filters are plenty good from a quality aspect AND are reasonably priced. Paying $15-$20 for a filter only being used for 5k miles is a waste, IMO. I pay around $4 each for Motorcraft filters in bulk numbersI didn't mean because they are cheap (their not) I meant because they perform better..I've seen some of the el-cheapo brands that the oil change places use that just would not flow oil

It happens more often, for whatever reason than you would think.
With todays cylinder activation and carbon from direct injection and oil dilution I wouldn’t risk it ! Not to mention low tension rings ! Vehicles are regressing back in durability of the engines ! And don’t get me started on undersized engines with turbos in large vehicles !The last 5 autos we have had all went well over 200k on 10,000 mile intervals.

my 1993 blazer would use 2 qts between changes moved from 5w30 to 10 w40 which is more appropriate for a 5.7 ltr with over 100k solved the issue !Low oil is generally not the fault of the oil itself, though. That's usually a negligence issue on the part of the owner. Barring a sudden failure in, or external damage to, the engine that causes the level to drop astronomically fast, it's usually just someone not paying attention that causes this.
However, in the case I cited- it CAN be a direct result of changing oil types, that itself can cause damage. The engine can be full of oil- but if something has caused sediments/deposits to break loose and stop up vital oil passages- having enough quantity of oil isn't going to help...

And it passed all of its emission checks untill it fell off the list due to age last one was at 143k which it passed with flying colors it now has 165k still runs great ! Have never seen the check engine lite or antilock break lite come on while driving !With todays cylinder activation and carbon from direct injection and oil dilution I wouldn’t risk it !

Well, I've risked it on the last eight new vehicles that I've owned. A quality full synthetic oil like Mobil 1 Extended Performance is easily capable of protecting an engine for 10,000 miles or 12 months, whichever comes first. Granted, I haven't put 10,000 miles a year on a vehicle since I retired but the Lexus GS, Jeep Wrangler, & Toyota 4Runner that I bought new and later sold to relatives now have well over 100k miles on them and have never had any engine/oil related issues. And they still get one oil change a year or at 10,000 miles with full synthetic per the current owners. No competent car manufacturer is going to recommend this if they aren't confident in the results. I remember when most people claimed that car and oil companies were scamming people into believing they needed an oil change every 3000 miles. Now, when those companies tell you that you don't need to do that, the same people argue that it needs to be done.With todays cylinder activation and carbon from direct injection and oil dilution I wouldn’t risk it !

Lab-tested oil samples are the gold standard for checking specific engine wear. Each metal has a characteristic origin within the motor.An oil sample might just save you a few $$.
I had one done on a diesel VW with 10,000 on the oil. They said change the filter and keep driving. Went 20,000 miles on that oil change.
Use it until it’s used up. When I had a job I drove 1,000 miles a week.
There is one caveat. If you are on a long road trip and need a quart or two of oil, get any good quality oil, even if it's a different brand than you have in the car. Please don't wait to return home to fill it with your oil stock. Use any API Service SN oil, preferably in your current oil's (xW-YY) weight range.In both cases, I always use the same type of oil, consistently. The biggest oil-related failures I've ever seen were from changing from one type of oil to a drastically different type- different additive packages and such caused disruption of the deposits inside the engine. I've seen engines that never burned oil, start burning oil, hydraulic lifter issues, and even stuff like bearing failures, because of this. Unless it's a fresh engine- just let it be, as much as possible. Pick a product type, and keep using it. It's not so much about brand- but about what's in the oil...

Part of the Gm cylinder lifter problems are from oil that’s dirty also the timing phases on the v6 and cylinder wear on the direct injection Honda CRV diluted oil all I’m saying is some of the newer engines due need 5k changes and some of the turbo models recommend 3 k !Well, I've risked it on the last eight new vehicles that I've owned.

Hmmm. I'm not familiar with the engines you're referring to. I've had both four-cylinder and six-cylinder turbos that didn't have those requirements. Must be brand related.I’m saying is some of the newer engines due need 5k changes and some of the turbo models recommend 3 k !

You can always change the oil and filter once you get home.
Yes, that is the proper preventative maintenance method.I always take at least one quart with me, wherever I go, in each car. That will usually tide me over until I can get more.
Same for power steering fluid, brake fluid, coolant and washer fluid, as well as a tire inflator compressor, and a ratchet strap. Got a bin in the trunk, they're always in. Also a toolbox containing all the normal hand tools, as well.
