Switching from synthetic to petroleum

[itsbob]

You can chastise me all you want... Mobil1 & filter @5k ...

Mobil1 I'd go at least 15 - 20k..

The best bet (and I think it's not offered) is to get an oil analysis done to determine when it was time to change your oil.

The Army does this with all their armored vehicles, and I know of some where we went well over 3 years with no oil changes.

The HUGE plus is, oil analysis always points to serious problems in your engine, it detects trace metals, and depending on the type of metal it detects it can point to where your engine is going to fail well before it actually fails.

I would bet well over half of us get out oil changed well before we really need to, adding to a huge amount of oil a year that either has to be recycled or disposed of.

Would be nice if places like Jiffy Lube had to test your oil first to see if it needed to be changed, before they dumped another 5 quarts into the environement, so someone somewhere had to drill and refine another 5 quarts to replace it.

Mercedes used Synthetic and cited 50k between changes..

People would change their oil, use dino and still try to get the 50k miles.. engines blew up, they sued, guess who the court sided with...

I thought with Synthetic the important part was the filter. You could continue to run the same oil, but the filter needed changed.. Amsoil (IF I remember correctly) used to advertise NO more oil changes!!

A couple "old school" mech's I know told me that synthetic oil doesn't necessarily need to be changed.

Instead of changing the oil at, say, 5,000 miles; just change the filter. Sounds good to me. :shrug:

Analysis is the way to go, really, but most folks cant be bothered to take a sample and send it in. Like Bob, wish there was a local option. I use Mobil One and do a full change every 6K.

BTW, folks stay away from Fram, Purolator Pure One, factory, or Mobil One, or a couple others are much better, and its worth a few bucks.

I also use mobil 1 and extended life filters and change every 6-7K miles depending! My supercharged car loves premium, thank goodness I only live 4 miles from work!
