Oil usage

Asked by Oct 01, 2019 at 10:47 PM about the 2010 Honda CR-V

Question type: Maintenance & Repair

I have 2010 CRV had no issues until last year with AC pump since then my
CRV has started using oil like crazy, what could be causing this? Did they do
something to my vehicle while they were fixing the ac unit? check engine light
is not on just checking oil very other week, no oil spots under car either we
have no idea where oil is going.  Also check fuel cap is now started to come
on?

Most invasive service involving the AC is compressor replacement, but even this wouldn't cause any increase in engine oil consumption. Oil consumption problems are due to faulty rings, valve seals, gasket leaks, and cracks in engine parts. If you're not seeing oil outside the engine, like puddles when parked, the oil has to be blowing out the tail pipe. If loss is excessive, you'll see black smoke out the exhaust on every start-up and possibly when the engine is running & warmed up. As there is no CEL on, it seems that this just started, but if left unrepaired, this will cause a misfire and might destroy the engine and catalytic convertaer. Have a compression test done to find out what's wrong. If the CRV is otherwise in excellent condition, it's probably worth $8,000, so if you need to install a used engine, that's economically feasible.

It's best to look for Honda certified independent mechanics. If you live in a an urban area, there should be several. If you can't find one, go to a Honda dealer.
