Hi, I'm looking for advice on Suzuki boosterjet 1.4 K14C (TGDI) engine oil. My use is mostly of medium journeys 20/30 km in the mountains and hills, average speeds of 40 km / h, occasionally long journeys, cool temperatures between -15 to +30 °C, at most 3000 RPM for 90% of the time. I would choose strict oil change intervals of up to 8000 km (5000 miles). I am interested in maximum protection from wear of the engine and timing chain, cleaning from carbon deposits on the valves given the direct injection, protection from any LSPI. Not having had a TGDI before, I explored the preferable oil specifications also in relation to what Suzuki recommended, it seems to me that a new API SP and ILSAC GF-6 would be excellent, in addition to a Dexos1 gen2 for petrol engines .
Minimum required specifications:
The oil qualities should be: 5w30 with the lowest NOACK and mid saps for the intake valves; molybdenum content to limit wear on the chain.
What I don't understand is which is the correct HTHS for this motor, equal to 3.5 for safety or it can go well> 2.9 given the Acea A5 / B5 recommended specifications. The first filling should have been done with (Suzuki) Ecstar f9000 5w30 or similar, hard to find in my area, it should have an HTHS> 2.9, these are the declared characteristics:
I have seen many brands but the one that most impressed me is the fully synthetic Ravenol DXG 5w30, except for HTHS of 3.1, with the following values:
Alternatively also Motul Eco-lite 5w30 but it looks slightly inferior and I don't know its noack.
Thanks in advance for the advice.
