WM Caprice.
First post on here.
Hello Hello
My VB WM Caprice 6.0 (dual fuel) is way overdue for a full service.
Any recommendation for best spark plugs and leads ??
Should I get new coils as well?
Does running on petrol and LPG effect what plugs and oils I should use??
I use penrite oils and coolant
Any help is greatly appreciated.

P.S. the plugs are really old
Possibly 7+ years old.
And I've never changed plugs before.

"VB" is a typo.

WM Caprice L98
My WM Caprice with the L98 is dual fuel. I have only ever used the standard plugs and leads. I have also always used 5W-30 fully synthetic oil of various brands (depends what's on special). Vehicle now has done just under 600,000 ks. If your plugs are really old, it might be an idea to spray some WD40 or similar around them and let it soak for an hour or so before removing them. You don't want to risk damaging the alloy heads.

As above the std ac delco stuff is perfectly fine, no need to replace coils if they aren’t faulty as for oil you’ll get lots of different suggestions but I reckon penrite hpr5 is the go
