My GF's Accent is, for lack of other theories, burning oil. Since it has had about 105000Km, I've notice oil loss on the dipstick. Around that milage, I changed the spark plugs. One of them was a bit oily from the top. I thought nothing of it.
The oil loss got progressively worst. It's my GF's car and she dosen't always check the oil level when filling gaz. The mitigation solution was to "try" to check more often and add oil as needed. Many oil changes, never saw oil leaks but unregular oil loss. No blue smoke. No puff on startup. Coolant was clean the 2 times it got changed (75000Km and 125000Km).
Had several CEL happen when very cold for 2y. End of march 2016, 129000KM, it got rainy and humid, car wouldn't start. Would turn and get some fire but not enough to start. Since I had gotten missfire codes before and reading on forums, I decided to order some coils and sparkplugs. 2 of the spark plug tubes were very oily. Had the valve cover gasket and spark plugs oil tube seals changed. The PCV was changed as well. I changed the oil at 130000Km and now it's 133000Km, there was a quart missing when I checked it (spot on at the L mark on the dipstick).
We've had that car since it was 3yo/33000Km from the dealer. It's been dealer maintained (with proof) for the first 3 years of it's life by previous owner. Since we got it, I was very meticulous with lubrications. Oil changes every 8000Km (as opposed to Hyundai's 6000Km), always using synthetics 5w20-5w30 (QSUD, PP, VSP, Castrol Syntec, generally a mix of those, spare oils from my other car). The only non synthetics oil used are for make up fills - generally QSAD 5w30. Using Hyundai OEM filter for those who care.
Car operates normally. No studder. Fuel economy is unchanged from when we got it - hovering between 6.3L-7.8L/100Km depending on time of year and cold. Operating conditions are between -35C and 35C.
Still can't find leaks. Can't detect smoke on the tail pipe. Car is white, bumper is clean. Should I think of using HM oil? If so, which?
WM, Canadian Tire and NAPA are the store I have access to. So QS Defy, Valvoline ML (red bottle) and Castrol GTX HM are the ones are available to me for sure. Which one is best and why.
