Re: Oil and filter for 3.6L
I've had 20 cars/SUVs and 6 motorcycles. I've only ever had one vehicle a VE Passat that burned or threw oil. I've used regular, semi-synthetic and full synthetic oil and never ever used anything but regular oil filters or fram but nothing special. I change every 5000 miles or twice a year. The motorcycles were changed sooner in mileage but only once a year.
Modern engines and modern engine lubricants should not burn oil. It's a fallacy that they should.
You should use the thinner oils to start with and with newer cars it's 5W-20W, unless you have extreme cold and don't have an engine warming unit, then 0W-20W is suggested.
I think people get stuck on the burning oil issues, but especially with V-8 engines.
If you want to spend the coin on Mobil 1, or the Purple stuff and that helps you sleep better at night then more power to you.
Modern engines, past 1995 were designed to go at least 300K miles with routine lubricants being changed when needed and bigger services at the 100K mark. Jeep Hemi engines are a bit different but they should go that 300K miles without needing an engine rebuild.
I think adding good magnets to the oil drain plug does a lot more than people give them credit for.
In aluminum alloy engines you want to change the coolant more often than recommended as the coolant may work 5-10 years but it doesn't have the anti corrosive capabilities for much more than 3-4 years.
Oil filters work and should be changed every time you change your oil if at all possible. Some other reasons oil adding might be needed is bad seals around the oil pan and other parts but today's motor oils are very good even the store name brands.
