I know another hydro oil question We talked about using Mobil 1 15-50instead of dino oil and the hustler additive. Does the synthetic Switch hold true for all synthetic brands or is there something special about Mobile 1? I'm thinking Mobil 1 is just the more popular brand and that is why other manufacturers are using it, but with their crazy pricing lately and the fact I found a place that has a great deal on Pennzoil Platinum full synthetic. I'm assuming Pennzoil 15-50 full synthetic will work as well. Please confirm so I can run out and buy all the cases I can get my hands on I'm scared to put just anything in these costly Hydro's and do not want to avoid warranty because I saved $3 a quart on oil.
