As far as the royal purple goes, not convinced. I've read more bad things about it than I have good. Apparently, it's comparible to a beer with a label on it that was printed off someone's computer. Sure, it'll get the job done, but what's it going to be like later. Been runnin the valvoline max life 5w-30. No issues here. Some people say it's a waste of money, but protect your investment. I change my oil myself, I never lose any in-between changes, usually just do every three months or less.
what brands of oil ???

so with me having 78k miles...would anyone advise for me to run synthetic? doing an oil change in a couple of weeks...read somewhere that someone changes oil after his 500 then run synthetic for the life of the vehicle. is this a good practice?

I run the Valvoline Maxlife 5w20 and a quart of the lucas full synthetic. Run it for 5k and change with new motorcraft filter. We run really hot dry days for most of the year around here and I do alot of interstate driving with a 20' car trailer, when I do change it the oil still looks almost new with no consumption between changes. Bought the expy with 82k on it and imediatly changed the oil noticed that the little bit of liffter tick it had during start up went away and also noticed that it runs a little cooler ( about 10 degrees ) the expy now has 105k on it and I have only had her for a year. My wife has a 01 Grand Prix that now has 190k on it have always used the same oil configuration but with fram filters and have never had a problem with it ( still gets 36mpg interstate driving at 80mph with a 3.1 v6 ). Just my .02 but have had great luck with this setup.

Mobil full synth'
As soon as I bought my current ride in 2008 (it was at 22000 miles) I was talked into going synthetic since the mileage was so low.
The first time I did the change-over I let a local lube shop do it.. They charged me $94 for oil and filter ! After paying I drove away telling the truck "enjoy it honey cause we're not doing that again in a hurry". Well I have to confess, over that 3000 mile period I got a 1.7mpg raise (I think it was attributable to the oil, I did nothing else different) and after a little shopping around I found I could change my OWN stinkin' oil and filter in Mobil-1 for less than $35. God bless Walmart. I got into buying a years worth and holding it in the garage.. $140 and I'm done.
Like it, my truck likes it, used it faithfully every 3000m ever since (2 yrs)
Pick a dry weekend and half an hour later it's done.

I run royal purple in mine, it's been great for years. Ran it in other custom trucks I've had also. I swear the expy gets better mileage than the regular stuff. Also run K&N oil filter.

just use what im using. gtx. works great. but i switched to high mileage just because i burn oil and i just hit 152,000. and a fram filter is great too. weight all depends on what you want. i like to run 5w30 cause i have engine knocks when its cold. valve sticking. if i run 5w30 it dosent knock but if i have 10w30 it dose. so i know its the oil. its always done that.

Update on this. I put 7 qts of Amsoil 5W20 and a Wix filter in last week. Then, I took a 370 mile road trip. I used to go about 340 miles on the trip meter before the low fuel indicator would come on. At 370 miles I was low but had about a gallon left when I stopped in to gas up. She also seemed to have more power on high speed acceleration. I'm sold on this stuff now!
