Good morning,

I read a lot of questions about oil quality, questions like;
Have you had any problems using this oil?

Have you done an oil analysis?

My question:
When are oil problems supposed to happen? How are they supposed to happen? Is this something that happens within a thousand miles or 10,000 miles?

I kind of think that if you put in the lowest grade fossil oil in your engine it would probably run quite good for some amount of time unless you have an inherent engine problem, like spun crankshaft bearings or valve guide seals!

How is one supposed to discern if a oil is destroying your engine in a very quick manner?

And would it really be the oils fault or just improper Machining or tooling on an engine.

This is why I believe that a properly broken in engine and clean oil will suffice for longevity of a engine.

I guess my question here is, I keep hearing did you have any issues using the oil?

How are you going to know that in a few hundred miles or even a few thousand miles you're not pouring acid into your engine!
Just trying to figure out what oil is the potential Nemesis of an engine in a short period of time!
Thanks in advance
 
Yes I get that, but it seems I hear the same statement a lot; are you having any problems with your oil. It seems to be a very open statement because how would one know if they're having a problem with their oil and it's causing engine problems. Even if they're using these certified oil because they all seem to be pretty much certified these days.

Some surprisingly aren't. Mannol is one of them and someone recently posted about how lots of silvery glitter drained out of his engine even though he didn't do a long interval and did a lot of steady highway driving both of which are the good case scenario yet it damaged his engine.
 
oil that meets vehicle manufacturer spec wouldn't be the problem lack of maintenance and recommended oil change intervals would be. any oil you'll find on the shelves of the auto parts stores or Walmart will meet current vehicle requirements even their house branded oil. I will leave it at this the oil wont fail.
 
There was a thread here recently, where the OP was complaining about oil consumption with a GM truck, and some knowledgeable members here recommend stitching from the recommended 0W-20, to 5w30, but that's one of the rare cases where it was at least half way clear that an oil different from spec was beneficial. This is not to say that the 0W-20 oil was damaging anything, though.

Is that what this question is about? Grade?
 
I have never seen a lubrication related failure.....where as an machine was damaged due to having the correct oil in it. I have seen failure due to lack of lubrication, lack of changing oil, and other related maintenance items such as coolant and fuel related things.

I think most comments are speculation without near 100% proof of anything. In my life, I have ran Mobil, Mobil 1, Valvoline & Napa, Amsoil, Royal Purple HPS, Supertech, all with my own subjective opinions.....that being said, it is not the brand you use, as long as it meets a spec, it is the manner in which you use the engine, and keep fresh oil and a good filter.

I will help you out, there are certain members posts you need to look at, not mine since I am always Wrong!
There is 1 Member here, I cannot beat him in a discussion on this Board, he did say 1 thing that was questionable, he would have flipped it around if I had called him out. This member gives me a lot of useful info, there will be a day when I have 1 up on this 1 Member.

I do not see this happening.

I will answer your question, use the Best Oil and you will find this out by reading everything on this Board. I had a Riding Mower seize on me, I will not mention the Oil, but it was a fuel issue.

I have used:

1) Valvoline conventional
2) Castrol GTX Dino
3) Mobil 1
4) Amsoil
5) Pennzoil Platinum and Ultra

This new Riding Mower is beyond the Break in Period, it is getting HPL CK-4 10W-40, should I have chosen:
Mobil 1 TD 5W-40
Mobil Delvac ESP 5W-40
Amsoil Small Engine Formula 10W-40
Redline 10W-40

The oil's I listed are what I used in my car, now I am using the best Mobil 1, Oil at least IMO. LOL
 
Only oil related failure due to quality I’ve seen was around 1981 when Quaker State had a recall on some oils. In cold temps it would solidify. The dealer I worked at then used Quaker State bulk oil. We lost a bunch of engines and Quaker State covered every single one of them.
 
Started turning wrenches in the late 60's. Never saw an oil related issue. Worked on everything from OTR trucks to P&W jet engines. It was always an owner/operator or a freak mechanical issue.

And also is my oil filter falling apart at the seams or did a clump of glue come discharged and is it blocking my piston oiling Jets . Girls used to keep me up at night when I was a young fellow .
 
If you are really worried about oil quality, buy one with more approvals or Euro approvals. M1 and Castrol Euro are on sale often.
 
Manufacturer rec oil is sometimes wrong. There have been instances in which the manufacturer altered its recommendation after engine problems arose. In general it has been appropriate oil. However a blanket statement in the USA does not take into consideration the driving condition of the specific car. Now with recommendations based on efficiency rather than maximum protection, I remain skeptical of manufacturer recommendations.
