Hey all, my wife and I have owned a 2014 Mazda CX-5 2.5L Touring FWD (Skyactiv non-turbo) since Summer 2016, from 54K miles up to the current 132K-ish miles. I've used OEM Mazda Moly 0w-20 oil and OEM Mazda filters, changed every 6K to 8K miles or so. Since 2019 I've also had Blackstone UOA's performed after every oil change. The reports have always come back looking good, except this last one where they say there may be coolant in the oil.
I have done all maintenance on this car since we bought it, and have not seen any oil or coolant leaking anywhere underneath. The oil itself on the dipstick looks fine, and what drained out last time looked fine. I haven't seen any loss of coolant from the reservoir tank. The car itself seems to drive just fine. Still gets 30+ MPG on highway trips, including our last trip to the Smoky Mountains in July, just after the last oil change.
BS suggests checking back in 4K miles. I'm wondering if I should get another lab to take a look at a sample. I just can't believe this car would be having head gasket issues already. The car has been nearly flawless for the 6+ years we've owned it, and we don't plan on getting rid of it anytime soon, if at all possible. What say ye?
Note that the oil it shows I added between drains on the report is mostly from either a top-end oil leak I had awhile back (VC gasket and oil control valve) and also the tendency for the factory oil fill spec to read low on the dipstick.
