Patrol GQ 4.2 - Engine Oil Recommendations
I read a few posts about GQ 4.2 Engine Oil Recommendations and wondered if anything has changed since then, I have a GQ 1989 Diesel 4.2 thats on 500,000km
Caltex Delo 400 Multigrade 15w40 seems to be a popular recommendation from posts about 7 years ago. (2010) but given that we are in 2017 has anything changed?

(Remembering diffs,g-box etc. won't take all those amounts as the gears hold oil.)

Back in 2006 there's a comment from AussieMav91 on another forum:
One thing to Look for in the old TD42's, the Oil grade recommended is a CF, The Current latest is CJ-4 for Low emission engines. If you run a Higher Grade than CF you run the risk of oil burning because as you go higher grades the Detergents increase. More detergents means less carbon build up, and in the TD's carbon helps seal them rings from burning oil. So be weary of that!.
I look forward to your recommendations.
