Q&A: Change oil based on mileage, not car readout
Dispute: We bought a new Chevy Equinox that now has 5,768 miles on it. The carrier computer indicates we still have 59 percent of oil life extant. In the past I have always changed oil between 3,000 and 4,000 miles. The relations advises oil changes when we reach 20 percent of oil existence remaining. We really like this vehicle, but I'm a minute nervous.
ANSWER: After nearly 30 years of doing this column, I've skilled that there are two basic categories of car owners: those who take care of their vehicles, and those who aren't interested or don't absolutely care. The fact that automakers now install "oil-life-force monitoring" systems, sealed transmissions with no dipstick, and wish-life coolants is confirmation that most owners tumble into that second category.
For all of us who do care, the oil monitoring systems compere a conundrum: Do I change oil when I want to, or when the car tells me to? There's no question that today's mechanism designs, manufacturing techniques, materials and computer controls run far more efficiently and generate far less debris and contamination, thus allowing longer oil and filter change intervals.
