Yeah, the original iteration of the HFV6 (Alloytec) was a dog, but even with the improvements I'd strongly suggest a more frequent service interval.
Yeah, 10k service oil change intervals with high quality oil... sweet as. Whilst I'm still not convinced that the HFV6 will ever be as bulletproof as the old Buick 3800 or a Barra, you're doing all the right things to give the engine its best shot.
I remember when 10k / 6m service intervals were the norm. To be fair it's not just Holden where the 15k / 12m service intervals come back and bite the second or third owner on the arse; most of the Euro brands are just as optimistic with their service intervals too. And yeah... plenty of people bitch about Toyota's 10k / 6m service intervals, but when was the last time you saw a Corolla made this century broken down on the side of the road?
I'd rather spend an extra hundred bucks a year on oil and filters than thousands on getting a fucked motor fixed or replaced because the previous owner was a bozo who did 5k a year and only got their car serviced every 3 years because they conveniently ignored the "whichever occurs first" part of the 15k / 12m service interval...
Yeah, oil is relatively cheap compared to a new engine.
As far as oil in a high mileage engine goes, I’m sort of in two minds about that. I chose not to deviate from the 5W-30 that these engines ask for with something heavier, and I feel like that was the right call. The engine was as quiet as a mouse when I bought it, and has remained that way after the oil change. The loudest things on this engine are the fuel injectors.
I don’t know what the oil pressure is, though, my scan tool doesn’t seem to have that, which is annoying. But there are no noises or anything with the 5W-30, so I’m of the opinion of not fixing something that isn’t broken.
What do you think? Would you go thicker oil in the same circumstances?
