I find Mobil 5w40 best tbh. I used Mobil Delvac 15w-40 from Bunnings at $87 and was good, also recommend in manufactures book. But I find 5w-40 to be best at least in my eyes. It runs different gets up to temp quicker and engine is quieter. Penrite Enviro 10w-40 is ok if you can’t get anything...
Hello to fellow Aussie, I was in same predicament and I also don’t like Penrite for engine oils. Their gear oil is good and I use EDS 5 for transfer case. Also 15w-40 imo is not too great for our engine.I use Mobil Delvac ESP 5w-40 in my 2023 Dmax and readily available from Oila.com.au.
