Envy you! I have 5 vehicles here, and only 3 are Fords. 2 Explorers!!! Hint is, in my other post today, there is a link, as the V6 SOHC engines have a plastic thermostat housing, and the dealer prices will kill a decent bank account!!! I buy on ebay, for $17.02, shipping included, the entire housing with all the parts already installed! Includes the new sensors and thermostat! Then get a bypass hose to trim to length, to match the old one at a local auto parts store. The ones I ordered on line were great, new, but, are about the same price as local ones. I am new here, today, but, I am 70 and have always bought used. New wears off when you drive off the sales lot, and it depreciates about 30+%!!!
One real money saving thing, WE only run 5W20 Full Synthetic Shell Oil, marketed as Tech Syn at Walmart, in 5 quart jugs for $17.xx. When used with the Fram Ultra Synthetic filter, it is good for 12 months, and up to 15,000 miles! That Ultra Filter is made of lambs wool, so it does filter synthetic oil. On the oil filter box is the warranty! it is $8.97 for most of he Ultra filters by Fram.
Having a fleet of 5 vehicles, we would pay $480 a year for conventional oil changes, in our driveway, so, we only spend a total of $132.25 using synthetic, a savings of $347.75, BUT, with synthetic oils, as from the factory these vehicles came, we actually get better economy.
Fleet Mileage testing economy, is why makers run synthetic oils and lubricants in new vehicles since at least 1996 (the rear axle in all Fords, and transaxles/automatic transmissions since 2000).
Many of our vehicles have 140,000 to 290,000 and run like new with synthetic oil! Ford transmissions run Synthetic Mercon, while the rear axles run a lifetime fill of synthetic lube. Expected life is over 500,000 miles! Volvos can do a million, so why not Fords, who "owned" Volvo so long!!!
Most maker's warranties since 2000 are voided if any petroleum oil is ever put into the engine! Proof is simply that there is a film of varnish inside the valve cover, and engine, and on the parts exposed to engine oil when they replace any oil sensor/ part at the dealer. Synthetic doesn't break down until it is hotter than 1375 degrees F, so, it never forms varnish in normal operation.
