Hi, I have a 3.3L V6 engine in my Sonata filled with normal mineral oil. I purchased the car brand new 4 months ago here in the UK and have done 2500 miles. I thought it would be a good idea to change oil after the break-in period. My dealer only uses Total Quartz 9000 5W-40 synthetic oil.
Some questions.
1) Anyone have any comments about this oil? The car manual states SAE 5W-20, 5W-30. I'm wondering if 5W-40 will still be ok?2) I read around the internet that it is a good idea to break-in using mineral oil and then change to synthetic. Any comments as to what a typical mileage would be to fill with synthetic?
3) Interestingly, my dealer also sells Citroen cars, and these come filled with synthetic from new. I read on the internet that synthetic is 'too slippery' to allow for proper break-in. I'm wondering if this adversly affects break-in/ engine life?BTW, the cost for oil and filter is 60 GBP
cheers, nick
