Vehicle is an 07 Ford Escape with the 3 liter Duratec, it has 138,000 km on it (85,00mi) and it runs like a top. Was given to me by my old man, it was always serviced at the dealer then a small indy shop that put nothing but bulk 5w20 in and WIX filters on it (oil changes every 5k) I had the oil changed before I drove the truck halfway across Canada, and have since put on several thousand more kilometers. It was done at about 130k km and the oil still looks fairly amber at 138. This is crazy to me, most vehicles I've owned have blackened the oil by 5k km or earlier. I also take several short trips a day (I drive less than two minutes to work) but when it's fully warm and I can, I rev the bejesus out of it. The 3 liter really isn't afraid of RPM. anyway, I want to run a full synthetic. I have a Walmart and Canadian Tire near me. Any recommendations would be appreciated! 5w20 is called for, the manual says this; XO-5W20-QSP (US) CXO-5W20–LSP12 (Canada) / WSS-M2C930-A with API Certification Mark thanks!
