Not for me, typically try to keep a check on things at oil change time which typically is around 5 to 6 thousand miles or 35 percent on our olm. Also usually a good idea to lube the door hinges and hood latch at oil changes.
Yes ! Another item I always check is the tires - INCLUDING the spare - when I change the oil. Nothing like putting the donut spare on only to find it has 10 pounds of air in it leaving it just as flat as the tire it's replacingAlso usually a good idea to lube the door hinges and hood latch at oil changes.
As stated, I wouldn't go over 5k - 6k between oil changes, unless I would know for a hard fact that you could go that long between oil changes. I've read the fine print on some brands of synthetic motor oils and it stated to refer to your car manufacturer's recommendations for oil change intervals. I check the tire pressures once a month and lubricate it every six months. Better safe than sorry. Yep, doing car stuff in the cold is a pain, but I'd rather be in the cold for a little bit than have to spend a couple thousand for engine repair or replacement!got an email for mobil annual protection. it appears to be 40 vs 22 for the synthetic bottle. i hate changing my oil and as i drive 33K a year i change it a lot.
also my valvomax isnt working right and thats frustrating too but thats for another thread. it only drips the oil out of the hose..sigh
so who would trust the car for 20K on this oil. it would literally save me tons of time and a bit of money and i do hate changing it in the cold months.
I would not go to 5 percent under any circumstances. I don't like it when I have gone under 30 percent olm remaining.since i use the synthetic and its black when OLM is under 5%, i guess in theory a lame test would be put the 40 dollar a bottle stuff in and see when OLM is 5% if its the same black?
i dont know where to/how much analysis would be. nor would i know if its ok to keep running on old oil
