Got a 06 tiburon with a 2.0 5 spd. 110k miles. Bought it with 100k miles, did two 4k oci's with pphm 5w30. In hopes to clean it out. I have no idea what the previous maintenance was. "Replaced All my fluids but brake so far" so a few questions. 1. What weight should i use? 5/20 5/30? It has some ticking from the hla's but not too bad. I live in washington state so winter can be cold and summer can be hot. Theres not really any good temps year round in WA. 2. My driving habit is cityish my work is 6 miles away and takes about 25 mins to get to. Max speed i see on the way is 50 for about 1 mile. I let my car idle for 3-10 mins before driving everyday. I usually shift at 4, 4.5k. "Makes good power at 2800-4000" no reason for me to go past 4.5k. Unless i get in my rare stop light race with a fellow import. 3. Oil consumption is about a quart or 1.5 qts in 4k "depends how hard i drive". What is the main cause of consumption? No leaks and no smoke. Thanks for reading. My current fill is still pphm and plan on a oil change at 112k. I use oem oil filters due to hla noise with these motors.
