Tomorrow I plan to change to mobil1 0w30 out for amsoil 0w20. I'll start by doing a flush using the amsoil engine flush. I went ahead a bought the amsoil oil filter too. It was only a few bucks more anyway. I'm not sure if I'll do the 25000 mile change interval though. I guess technically the engine doesn't drive my car the full 25000. lol
Surprisingly the amsoil was only $7.70 quart. I thought it'd be more. I think I paid about $6 for mobil1 and eww! I don't like my money going to them. $45 is a little steep for an oil change but I'll just do half as many.
"I personally use Mobil 1, 0W-20 in the 575 Maranello and for the first oil change I drained the Murcielago?s 5W-40 Agip and replaced it with 0W-30 Mobil 1. The engine became much quieter. A valve tappet noise disappeared. I may try the 0W-20 next. For all my other cars I use the regular Pennzoil Multigrade 5W-20."
Well I talked to the rep about it before I went with it. He wasn't too concerned(he's been selling it since 1979). I was going to run 0w30, but as you said the 0w20 is a bit cheaper. It also is rated for a shorter life cycle. I was running m1 0w30(mixed it up myself) from walmart. I don't think I'll have a problem. I hope not anyway. This ain't a ferrari thats for sure.

wow, too much info on oils. So my oil filter was changed 3,000 miles ago, I only need to change my oil? What about fall weather. 40 weight prolly not the best for my engine on a sub freezing morning, right?
May be doing an oil change in the morning.
Amsoil actually makes some very good products. The negative image of Amsoil is due to their distribution method (MLM) and their marketing approach. If Amsoil products were competitively priced with Mobil 1 and other synthetics, and if I could buy them in a store, I would not hesitate to use their XL-7500 synthetic as opposed to Mobil 1. What upsets me about Amsoil is that they didn't disclose until recently (and then it was by accident) the real reason that their oils (except for XL-7500) are not API certified. In the past they came up with all sorts of bizarre excuses about the reason for their lack of API certification and this greatly contributed to the distrust that people have of the company." --http://www.nordicgroup.us/oil.htm#Which%20Oil%20to%20Use
You won't regret using Amsoil! My wife and I drive 3 vehicles a total of 65,000 miles a year. I switched to Amsoil so I could take advantage of the extended oil changes but was pleased when I gained 2 MPG by switching to Amsoil 10W-30 Synthetic in my 01 Chevy Impala. The oil was changed at 201,000 miles and with 204,000 miles it still looks new. I also ran Amsoil’s “PI Performance Improver Concentrate”. Now the engine runs like it did 130,000 miles ago. The Amsoil 10-30 and filter are rated to 25,000 miles but I plan to sample at 15,000 miles the first time since my engine has so many miles on it.
