OK guys! I did it! I'm gonna make the switch from regular 5-30 to full synthetic 5-30. I need help though. I am completely new to the synthetic oil. Is it OK to just dump the old stuff out and put the new synthetic in? Or do you have to flush it or something else? Also, How long do you guys go before changing the synthetic? I have always religiously changed the oil in our cars at 3 months/3K. Whatcha think? Oh also, I have an oil pressure sensor to replace. Any input on how to go about that? Or any advice?
Thanks guys

I'm guessing no flush needed, just swap it. I run the 15k stuff but I change it out about every 30+k (a bit on the extreme). I'm running mostly highway miles and she's got 161k on her. So anything better than that (more frequent changing) is a plus.

 

Nope, no flush needed. I run Royal Purple now after 20+ years of using nothing but Mobil 1. I run it with either a Wix, Mobil 1 or Purolator filter and change every 6k miles...

 

Pour old oil out and pour new oil in. Get a descent filter and change every 5-10kmi depending on driving habits.

 

+1 on the oil. I run RP with a Mobil1 filter and change every 5k.

 

Thanks for the input! I don't think ill ever go over 5500mi without changing my oil and I use the Chrysler filters only!

 

Yea don't do what this guy is doing...30k on an oil change is ridiculous. I guarantee your engine is sludged all to hell..

 

yea really 30k is insane. even for synthetic.

 

Every 30K, HOLY SH*T. The oil has to look like tar when you drain, its a wonder you dont have to dig it out of the oil pan with a screwdriver

5,000 is the most i will ever go, synthetic or dino oil

 

The oil pressure sensor is threaded into the block right under the power sterring pump. Pull it out, put in the new one and enjoy a working engine.

I haven't don it, But I am about to change from dino oil and goto RP. I just found a local supplier for it, So in about 2K miles I will. just drain the oil out, Pull the filter and put in the new oil and filter. Replace the next 2 changes at the regular 3K mile interval, After that you can extend your changes a little. The leftover oil in the engine doesn't hurt the engine at all.

PS, If you are burning oil at all, get it fixed before you goto synthetic, The synth oil is a bit more solvent than dino, otherwise you are home free.
