I live in a complex where tenants aren't supposed to work on their vehicles, plus the oil filter is a real bitch to take off/put on on the 3.0's. His prices are reasonable too, a basic oil change is $21.
That never stopped me, lol....
I lived in an apartment complex for awhile that specified no working on vehicles. They did allow two vehicles per apartment though, so I had two vehicles that I parked at one end of the lot. I always parked the one I was going to work on at the very end and parked my other one next to it, so nobody could run into me without hitting my other truck first. I did oil changes, brakes, tore the interior out and completely rewired the stereo with new speakers, tinted windows, etc.
I was also the yahoo with four mud tires mounted on rims and chained to the roof support post outside my apartment door, lol.
They never gave me any trouble till the last couple months of my lease, and then it was that they got on me about living by myself but having two vehicles in the parking lot....
So I sold my stock 1989 Bronco II Eddie Bauer (wish I wouldn't have done that). Had one truck in the parking lot for about 3 weeks, long enough that they started to forget....
Then I brought my choptop up, got it caked up in mud then parked it on the upper end of the parking lot so when it rained the mud washed down through the lot, lol. Never heard a peep about it, lol.
But yea, 5w-30 will not harm a thing.
