I guys, first post here and I'm very green when it comes to the chemistry of motor oils
I've just bought a new 2.0L Hyundai i30 which is the sport version here in New Zealand. We get the typical mild 4 seasons here with average winter lows of 2 degrees C for 2-3 months and average summer highs of 25 degrees.
My car has done 1200km and I'm going to put a good oil catch can in place to help reduce inlet valve carbon.
The manual states 'for best fuel economy' use 5w30 ILSAC GF-4 (API Service SM) or above, ACEA A5???????? what ever that means. Hyundai seem to recommend Shell Helix motor oils.
I've also read that to reduce inlet valve carbon build-up, a low SAPS oil is good. Is this because it doesn't become airborne as easily so less oil will get vented via the PCV to the inlet manifold?
What would you guys suggest as an excellent oil for a modern GDI motor that falls into spec. I also hear that thin oils are bad for GDI so based on the 5w30 'for best fuel economy' comment (thinner is better for fuel economy), if I didn't care about fuel economy but cared more about protection (that high pressure fuel pump running off the cam is fast and brutal as is the overhead cam chain), what would be a synthetic oil brand and grade you'd recommend?
I'd change the oil every 5000km or year as per the maintenance manual.
Thanks for your help.
