What type of oil do you use?

[88Racing]

This poll is multiple choice so if you run more than one type throughout your multiple vehicles you can select which choices you want to vote for.
Example: If you have 3 vehicles and run all three types, then pick all three types. Or if your doing winter/summer type switches, then pick both.
Multiple choice poll, pick as many as you like but you only can have one shot at voting on it.

I always had my oil changed at my Ford dealer. I then switched to Mobil1 full synthetic. After 1500kms yes 1500 my truck started to leak a large amount of oil from the pan area. I have now switched back to Ford 5W-20.

Because of all the problems with the Cam Phasers and oil related issues, Ford does my oil changes on my 5.4L.
