I have 99 Caravan. I put Monroe "Premium" strut assemblies on it 5 years ago. They make a loud groaning noise when the temp falls below 40 degrees F. No more Monroe for me.
Didn't we just have paper published by GM on here say that by far the most important wear factor is cold starts and oil type and grade were of little importance.
Walmart oil and filter will work well for %99 percent of the cars on the road.
Until May 20th. 5 liters of their OE synthetic oil [made by shell?] and an OE pro-series oil filter. This is a very well made filter. Ya never know when the price of motor oil is gonna rise.
How long can an engine last when treated this way?
Remember, no good deed goes unpunished!
She puts in some of your used oil. The next day the engine seizes, then what?
Do I think the GDI engine in my 2016 Hyundai is a good engine? Absolutely not. Do I change the oil more than any other car I have owned? Nope. You can't fix a poorly made machine with slightly cleaner lubrication.
I think it's more about the design of the structure where the wheels retract up into. Put the equipment in the cheapest/easiest positions and make the gear conform to what room is left.
Maybe you're right. They look perfectly good at twice the recommend change interval.
You've convinced me, I'm not going to change my air filter this year. It feels better to just sit down and have a beer anyways.
I run my air filters about twice as long as the owner's manual specifies. Air filters do a better job as they collect dirt. This way my engine is in better shape and I've saved time and money. Drives the same before and after the filter is changed.
