Just wanted to say hello, since I am a new member. I was curious if I am using the right kind of oils for my vehicles, taking into consideration of how they are used. Here is what I have got:
97 Subaru Outback, 2.5, 90K mi. I have been using M1 10W30 and and a PureOne filter every 6K mi or 6 mos. This car is driven good bit, about 1500 mi a month, mainly highway driving.
2000 Ford Ranger, 4.0, 70K mi. Been using M1 5W30 and a Motorcraft filter every 6 mos. or 6K. It usually ends up being close to 6 mos. as it isn't driven far. I was using 0W30 but it made too much noise.
1972 Ford F-100, 400 ci, 30-40K mi on motor (guessing). The motor, although with low miles, blows a lot of smoke under hard acceleration. I think it has a nicked ring on the one back cyl as it fowls plugs sometimes. I was using PZ 10W40 and a PZ filter but it seems like its always low on oil. I was thinking of using PZ SAE 30 this spring as it's only driven April - Sept. Would 15W40 have similar results?
