Oil change interval advice from Ask Rob About Cars

The shop where I have my car serviced has been urging me to change my oil in my 2013 Mustang GT California Special more often. I've owned this vehicle since May 2012 and have 11K miles on it. Since I don't have time to drive it much I change the oil once a year since Ford recommends every 10K. The question is should I change it more often or is once a year with synthetic oil okay? Thank you, Russell in San Jose

Answer: Russell, modern engine oils and engine technology allow for the 10,000 mile oil change intervals. Keep in mind the manufacturer also offers a powertrain warranty for up to 100,000 miles so a 10k oil change interval is not harmful under “normal” conditions.

If your trips allow the engine to fully warm up and the oil temperature to get over 200 degrees regularly to evaporate moisture, you’re probably just fine. Keep in mind the manual says to start the engine every 15 days and allow it to reach normal operating temperature.

Ford puts particular emphasis on their oil life monitor stating a the oil change must be done within two weeks or 500 miles of the ENGINE OIL CHANGE DUE or OIL CHANGE message. Should the monitor be accidentally reset or inoperative, Ford states to change the oil at six months or 5000 miles and never exceed one year or 10,000 miles between oil changes. More extreme use as described in your manual will require more frequent changes and the readout should reflect this.

If you want laboratory data to compare, I highly recommend Blackstone Labs for a $28 oil analysis www.blackstone-labs.com. What would be interesting is how the oil life display readout correlates to the vehicle miles and the lab analysis.

Sixth generation Camaro V6 review

Chevrolet updated the chassis of the Camaro for 2016 with the new Alpha platform and by all accounts the approximately 250 to 300lb weight reduction was a huge improvement. Despite having a brilliant chassis and three powerful engine choices, the interior and outward visibility hardly improved at all. I wanted to like this car, I really did. It has some really good aspects but overall it’s only good for going in a straight line, not reverse or backing up out of any parking space, on public roads or modified into a track-only car.  You decide if the interior justifies a $29,000 MSRP. The 2017 model is essentially the same. The 335hp V-6 is a great engine, responsive, sounds good and with the quick shifting 8 speed automatic, the car is capable of mid-high 13 second quarter mile ETs. It feels every bit as quick as the numbers suggest. It has no appreciable dead spots and has an excellent pull. The 8 speed auto is finicky on the highway though, downshifting at the slightest provocatio...

2015 Porsche Cayman GTS review and test drive

The 2015 Porsche Caymen GTS is the now the best all-around sports car under one hundred thousand dollars, replacing the prior title holder, the Porsche Caymen S. Take everything the prior S model is, add horsepower and a more track and driver oriented, visceral demeanor while retaining streetability, and that is the GTS. Besides horsepower, it adds a new body kit, a sport exhaust system, 20” wheels and a lower ride height versus the S. Conveying the balanced perfection of a Cayman isn’t easy unless it’s driven. The latest generation gives it a more exotic, grown-up look. Inside, the familiar ideal seating position with excellent outward visibility. Every surface visually sculpted, everything that is touched has an engineered quality with logic of the controls. For performance driving or track days it has a lower ride height, among the lowest center of gravity among production cars, and an engine placed where it’s supposed to be, right behind you. The sport exhaust reminds the driver th...
