That said, I've been doing it now for 8 years and over 160k. So far, so good at 206k. I know the 10k oci is hard to imagine to some of you, as you've expressed. I'm not telling you what you do it wrong or unnecessary. My reasoning was not made lightly. I've been changing my own oil for 40+years now and was raised around the 'oil' business. I remember the first synthetic oil that came out in the late 70's. I will just say I researched and read alot about the new synthetic oils before deciding to use it. Now the other consideration was the cost effectiveness. I average 20k miles per year, so at 5k oci, I was changing oil every 2-3 months. The synthetic oil costs ($4.60/qt) roughly twice what dino oil does. At least it was at one time! It may be higher now! I now change my oil about every 6 months / 10k miles. I don't have the time or space to go into the reasons for oil failure, but let's just say two major ones are heat and contaminants from the combustion process. I believe the oil industry has engineered much better oils/additives in the last 10-15 years to enable the 10 to 15k oci to be possible. Even in a quart of dino oil, it is mostly additives now. It was hard for me to eat oysters and squid the first time, but I lived. Thanks to the Jack! I'm just here to tell you it's OK to try a 10k oci. The real question or weak link with the 10k oci is what this thread was all about. Getting the very best oil filter to go with the 10k osi. What is the best filter out there for a 10k oci??
