Hey guys i just clicked over to 61k and ive heard from a few post and a few friends that it is better to run a 5w-30 oil instead of the 5w-20 when we get a few more miles, which one would be best any other thoughts? different weights or brands? or just stay 5w-20

Until an unbiased, unsponsored, scientifically controlled series of tests are done and published there is one answer:

Any synthetic.

The only constant should be that you stick with the brand you choose.

I've got over 100k on the clock and only use Mobil 1 5w20. I wish I still had only 61k.

I just clicked 86k and i've been running Mobil 1 5w30 since 60k with no problems.

100k is really not a lot of miles for our engines. Stick w/ what you have been useing, synthetics are much better.

oh crap i wish synthetic would work for me i hear how everyone else makes out great and how good it is, and i was at 36k i made the dumb decsion to switch after my car had miles on her and it caused my IAC and a a couple of clogs i dont know where i forgot but the mechanic said that the syntheic oil was so clean that it pushed out all the dirt and clogsand left deposits and so i had to go bak to the dark side of regular Penziol 5w-20 motor oil! is this penziol oil any good ive never had a problem with it yet

pennzoil is a wax based oil, yuck[:'(]

Try synthetic again, but I personally think 5w20 is too thin my for climate, in im Houston, I use 5w30 year round and always will, its just a good universal oil. Whatever type of oil you use, it would be OK to switch to 5w30

are all convetional oils wax based i mean my motor can see 160k out of using this oil right?
