I tend to agree, I just found it interesting that even when I asked Valvoline Australia technical about Valvoline Restore and Protect and wet-belts they basically said no. Have a look at their reply:
“Good morning, most Ford Eco-Boost engines require an engine oil meeting Ford specification of WSS-M2C-913C/D, eg, MD Mondeo with a 2.0 litre, Mustang with 2.3 litre, LZ Focus with 1.5 litre, WG Fiesta with 1.5 litre, FG MK II G6E with 2.0 litre, Escape with 1.5 litre, the Valvoline Restore and Protect 5W30 meets Ford requirement of WSS-M2C-961-A1, so in these applications I have mentioned, I would only recommend our Synpower FE 5W30 as it is approved by Ford globally for WSS-M2C-913C/D.
Hope this helps.”
I then asked about the newer EcoBoosts which spec 961-A1 and the reply was:
“Good morning, the Ford Ranger Raptor with the 3.0 litre engine, we currently do not have any information on this vehicle for Australia & New Zealand from Ford, it is a relatively a new release for the US market and requires a 5W30 full synthetic engine oil that meets Ford approval of WSS-M2C-961-A1. Valvoline Restore and Protect 5W30, and Synpower Full Synthetic 5W30 both meet the Ford requirement of WSS-M2C-961-A1 but are not approved. I suggest that you check and confirm with the vehicle manufacturer on the warranty obligations before using the product.
Regards”
I think I’ll run it anyway, it’s my own car, and if there’s an issue with the belt prematurely degrading then I’ll deal with it, but Valvoline’s response leaves me a little concerned.
