I finally found where to recycle used oil near where we moved. I had accumulated about 5-6 oil changes on our three cars and the container was full. I've been doing 6000 mile OCI with Super Tech 5w-20 FS. I switched to ST FS about two OCIs ago. Have been using Motorcraft FL500S filters. This is for my car: 2009 Lincoln MKX just hitting the 100K mark. In Walmart I saw ST 0W-20 HM FS and QSUD 0W-20... $2.00 difference. ST FS HM is $15.98 QSUD FS is $17.98. I went with the ST FS HM and a ST filter for $3.00 for my next OC. Zero leaks, quiet, my SUV has been running great but the QSUD seems like a bargain. I've still got 3K miles before my next OC on that car. Is the ST FS HM 0W-20 the way to go? Spec by Ford is 5w-20... but my next OC will take me through the Winter here in SE PA and 0W-20 is a positive change I think. Next up is my wife's 2016 Lexus ES 350 with 25K on it and balance of factory warranty. I bought the OEM Toyota filter cartridge and the filter wrench but have held out on the oil as it was changed when we bought the car in April. I am thinking that the 0W-20 QSUD would be perfect for the Lexus when I do a 5000 mile OC in probably October. That would likely be almost an annual OCI as the car doesn't really get driven much.... Maybe 6500 miles per year and Lexus says 7500 mile OCIs. Thoughts /input?
