My plan was to do my first oil change around 2500 miles with Valvoline 5W-20, wait until 5000 miles and then start using Mobil 1 Synthetic 5W-20, and then change it every 5000 miles thereafter. I have a few very strong refrigerator magnets stuck to the oil pan near the drain plug to help keep...

Thank you, everyone, you've all provided a wealth of information. I've never done a UOA on anything I've owned, I will probably take the advice of just waiting til about 2500 to 3000 miles and change it then. I know no one would just build a motor and just throw it in a vehicle without running...

Sorry guys, I have the 5.0 V8

I was thinking somewhere around 500 miles, maybe even 1000 miles.

Hey guys, I just bought a brand new 2017 Ford F-150 two weeks ago. I'm just over 400 miles now, and I would like to change the oil soon, just from "breaking it in". Is this something I should do, or am I getting too carried away? I will eventually use synthetic, but for the first oil change I'll...

Thanks everyone, you have all been a great help. My dad has worked on cars since he was young and always said Pennzoil and Quaker State were no good. But like you guys have said, they have come a long way. And yes, dealers frighten me with the things they do and try to pull. I heard somewhere...

Hey guys, so I have a 2011 Jeep Liberty with the 3.7L V6. I've been using Mobil 1 Full Synthetic 5w20. I've been changing the oil myself but because doing an oil change on this thing is such a major P.I.T.A. (no easy way to do it), my wife thinks we should let the dealer do it. They supposedly...

Thanks for the replies guys. I've used 10w30 in everything I've driven, including my current vehicle, a 2000 GMC Sierra 2500 with a 6.0L and 193,000 miles with absolutely no drips or leaks. That's why I said I've had great success with it. I truly didn't think it would hurt anything either, but...

Hey guys, I wanted to ask about oil viscosity for my wife's 2011 Jeep Liberty 3.7 V6. I changed the oil tonight using Mobil 1 Synthetic 10w30 in the 5 qt. jug. I know it said to use the 5w20, but I like using the 10w30, and I've had great success with it. That should be fine to use, ya think?
