Do you change your own oil?

 

we're on first name account with the local oil depot, because the hemi goes in every 3-5 weeks plus a firebird, dakota, and dually. We've known the owner since we moved to texas, started as a Uhaul center + one bay, and now it's a 6 bay depot with a fully automated tunnel car wash and 5 truck towing fleet.

Cool. I like pennzoil. We've always run pennzoil until I got this truck. My father gets it by the case from work and its been a good oil. I just wanted a high milage snythetic blend and pennzoil doesn't make one so I went with valvoline.

 

personally, i think synthetic and high mileage don't match.

A high mileage motor will have piston slap. I would think synthetic oil would have no problem filling that gap into the combustion chamber...

that's why we run such high viscosities in all our vehicles. I wouldnt be surprised if we switch the hemi to 10-30 by 200,000.

 

5W-30 Castrol Syntec (full synthetic) for me, with a tough guard heavy duty oil filter.

 

Its not fully synthetic its a synthetic blend. And that won't happen. And by high milage they consider 75k and over high, which now in days isn't really that high. Iv never heard of someone having oil getting into their conbustion chamber because of using synthetic. The only problem Iv heard of is changing fully synthetic too late it it actually working too well. And by that I mean cleaned all the build up out and clogging the oil pump.

 

Are you talking about the fram one?

 

ya i have heard that also, with engines that are really old and have a ton of miles... if you go synthetic, just don't change back or else the new mineral oil will **** up your engine like no other.

 

ya thats the one.

 

I heard those a no good... forgot why though
