5W-40 engine oil okay for 6G74?

[Sharkie]

i've been putting 5w or 10w and had no problems at all.

i've been putting 5w or 10w and had no problems at all.

i got 5w-30 in the TL, its only after a couple of days of not driving that i'll get noise for about 20-30 secs at most, otherwise its alright. But like mentioned earlier had 5w-50 in the TF and no noise, I just wondering is it partly due to the slightly more aggressive cams in the TL that may play a small part. Perhaps someone with knowledge may shed some light on that.

I runs Penrite HPR5 5W-40, engine seems to like it. It rattles for a second or two on a cold start and it ticks when warm but that's because the lifters are buggered, not the oil.

I use Penrite HPR10... engine is smooth as a .............. <- fill in blank

I'm probably going to run Mobil 1 5w50 in mine like Alan suggested. I've done 1,500km on the "Aegis" oil supplied by the mechanic who did the presale service on my car. Now I only have to decide what filter to use. Any suggestions guys?

5w are the cold viscosity and in fact the lower the better (0w) which improve startup protection, the thickness of the oil are the number behind. Be it a 0w40 or a 15w40, they are still a 40 weight viscosity oil at 100'c engine operating temperature.
