I am going to change to it tonight. I wonder if it will help with oil consumption? I guess it doesn't breakdown as fast. I will still change my oil at my normal intervals.

Im not a big mobile one fan, if you have many miles, that **** will blow right by your pistons

I've used mobile one in all my cars and I like it. One of my cars has over 200k miles on it and the oil didn't blow by the pistons.

I changed to the extended mobil one from regular mobil 1, and I also went from 10w30 to 5w30. I noticed my oil pressure is a little higher driving on the hwy (5 psi more) but it is the same when its cold, or at idle. I still change it every 3-3500 miles. Mine has 133k on the clock, and it has the normal ls1 oil burning (1 quart or so every 3k miles, hope thats normal).

I'm skeptical of any brand of oil that you can run longer than their regular oil. All oil marketing preys on your conscious. Run what your conscious can afford. Personally, I'm not running anyones oil more than around 3k, no matter what is says on the bottle or commercial. But then again, I run Wal Mart 10-30. LOL

Check www.bobistheoilguy.com under the Forum section. There is a section where people post wear analyses. There may be some reports on this oil for LS1's over there by now. The best oil for LS1's and LT1's is the Castrol German Syntec 0W30. It's a thick 30wt that's about like a 40wt. Only Autozone carries. To distinguish this from the regular 0W30, check on the back to see where it's made. If it's made in Germany, it's the good stuff. If it's made in the U.S., it's not it. The U.S. version is just regular dino oil that's been processed more but can be classified as a synthetic even though it's really now.

The extended mileage oils have more robust additive packages. That means it lasts longer (thus the word "extended") before the numbers go bad. If you are into extending your oil drain intervals it would be a useful switch. If you're figuring what kind of deal you're getting down the the tenth of a cent, I have no idea whether it's cost effective.

I haven't used any. I use Mobil 1 and change every 5k miles. Synthetic oil really does work for longer periods than 5k miles (regardless of what skeptics say) and there are any number of folks who have posted their oil analysis and mileage numbers to prove it. The old saw about "Oil changes every 3k miles or your car blows up" was useful advice decades ago (before detergent oil was invented) but modern oils last longer, and (true) synthetics last MUCH longer.

85K on the clock here, and she's had Mobil 1 5W-30 since day one. Maybe every 4 or 5 oil changes I might need to add a quart if I've been really beating on it. I change my oil between 3K & 5K, depending on how it looks and how hard I've been driving. I put Mobil 1 in my wife's SUV, and one time when I checked the dip stick it was clean as a whistle. Gave it a quick oil change, and never had an issue. That's really why I always buy Mobil 1 still...

i like using 5 quarts of royal purple 10w30 and a quart of lucas pure synthetic, supposed to slow oil consumption

All the Lucas really does is make the oil thicker. It doesn't make it more slippery or anything like that. You'd be better off going with 6 quarts of 10W40 with no Lucas. That's about what your current combination is giving you, and it'd be cheaper. That Lucas synthetic stuff isn't cheap.
