So, have we come to a conclusion on standard vs. synthetic??
And if synthetic, when to convert??

 

I'm a huge fan of regular. Change it early, change it often. Even though synthetic holds up longer, it still carries any dirt and metal shavings in it. If you're doing it frequently, regular's much cheaper.

 

I'm running standard now. In my previous ride, '99 Tahoe, I converted to synthetic around 90k and it ran strong up until the trade in for the JK at 177k. I think it was the right move to make and may make the change earlier in the life of my JK.

 

dino oil...

 

Synthetic without a doubt.
Changed my 94XJ over at about 5K miles. It's been running great with no leakes since 95.
Already switched the wifes 07JK over at 3k.
Next thing will be the front and rear diffs, most likely around 10K.

 

Synthetic is kicking some @ss now.
Keep em coming

 

after those posts im going syntetic when i get meh Jk

 

Yea, picking mine up on Friday (6 more dayz), thats why I started this poll.

 

Since I usually change mine at 3K, I see no reason to splurge on synthetic. Remember, the main idea behind synthetic was it's longevity. If you change at 3K like I do, then you're just wasting money. If you opt for a longer interval, then it's probably a good idea.

 

If you read up on synthetic oil theres some good things it does for your engine too.............
