Quote: It is short trips for the most part. Taking the kids to school, 4 miles down the road then picking them up. Once a week to my daughters physical therapy which is 24miles up the road. Once a month to Occupational therapy to Jacksonville which is 60 miles down the road. The rest is around here on country roads and several trips to her parents house which is only 2 miles away. Yeah, but that doesn't sound like 24k in 13/months. My...

As I said in the other thread, the Modular engines use bi-metal bearings. They have NO COPPER OR LEAD in them. So Blackstone is out in left-field here. Has this guy ever run leaded race gas? An injector cleaner with some lead in it? Any oil additives? Has the engine (or part of) been apart and a copper silcone sealer used?

Will re run the amsoil after I go the 5K on the Chevron I have in there now, then will run the amsoil for 6 months drain, and run the amsoil again and will decide then if I will go a year or just do 6 months and sample. I guess if I want to compare 1 year intervals I would have to do 1 year. But who knows if my driving conditions will be the same or not.

This one looks good, but I ask because I posted a similar question in the PCMO forum a few days asking if anyone knew if thicker HDEO lowered the copper levels for LSx engines. I tought this UOA looked like a lot of ones ran with...

Just trying to post my report instead of a link to it.

Going from a 5W-20 to a 5W-30 didn't seem to help copper much if any. It is trending down on its own I'd say. I doubt a thicker oil would help any. I'm sure it won't hurt to try either. I've been very happy with PP in my car. If it spec.'s 5W-20 why not try PP 5W-20 instead of the 5W-30 and see how it works?

I would stick with M1 or try Motorcraft 5w20. These numbers are nothing to be concerned with at all. There are quite a few guys on the Mustang forums that have over 150,000 miles on their 05 GT's (driven hard) using nothing but Mobil 1. I wouldn't put too much into this report. Run M1 again, and if it doesn't drop, switch to Motorcraft.

We also know that 2006 was the first year for 5w-20 to be used. Any other mods who knows? I have not seen anything factual. Since I've had excellent...
