The owner's manual stipulates 5w-30. I'm thinking of using 0w-30 Mobil 1.
I'm interested in knowing what, if any, might be the experience of others here.
Hello Parklane, I am an Amsoil dealer and I can answer any questions you want concerning oil.
Can I ask why do you want to go to 0W30?
What part of the country do you live in?
I personally do not recommend for Subaru's a change in viscosity unless extreme weather is involved.
Mobil 1 is a good oil for an off the shelf synthetic. I recommend the following, Amsoil Signature Series for Subaru's that are good for 25,000 miles between changes. The filters are good for 15,000 miles. Under normal driving conditions I change mine every 15,000K or 6 months whichever comes first. I replace what the filter removed and then close it up with a new filter. I then take the oil directly from the filter and have it tested for life. I have never received back a bad oil report even after sending samples to two labs.
