Here is the first analysis of my 2004 300M Special. I had done a couple of oil changes on it prior to this sample. The older information is from my 1999 300M which was totaled in February. Anyhoo, here it is... Any thoughts??

Here is the latest analysis on our 06 Focus. Everything looks great!! Blackstone Labs did the analysis: Any thoughts??

Group, I have read (and heard) that the diff's in our cars require Dino Diff Fluid due to the seals in the diff are not compatible with synthetic fluid. I ran synthetic diff fluid in the 99 forever with no issues. When I got the 04, I originally put synthetic (Mobil 1) 75W90 in it. I changed it...

Group, Over the weekend, I did some work to my car that for safety's sake, required me to change the oil. I did have M1 high Mileage 10W30 in the car (all WalMart had at the last OC. This weekend, I was at a parts place, and didn't feel like going to Wally World, so I got 5 qts. of M1 0W40. I...

Group, I am going to do an oil change this weekend on my 2004 300M Special. I am going to do a seafoam treatment, then do a engine flush....I wanted to get M1 10W30, but the local WalMart only had the M1 High Mileage 10W30. I am assuming that the only difference is the additive pack. Is this...

Here is our latest analysis on our Focus, everything is looking great!! Any thoughts??

After running an engine with extended high temperature exposure...I decided to dump the GC 0W30 in favor of Royal Purple 5W30. What are your thoughts on RP?? I have a sample of the GC 0W30 to send into Blackstone, but wanted to wait until payday to send it off. I am curious to see what 20-30...

Second oil change on the car. The first oil change was at 570 miles. Using a Motorcraft FL-910 filter. Oil is Mobil 1 5W20.. Any thoughts??

Group, Here is my latest analysis. Changed the oil after half the racing season, and 2 road trips. Also, about 40 passes at the track. Whaddya think:

Group, I am trying GC in my 300m for the rest of the year. I had Mobil1 0W40 in there for 6200 miles. I sent a sample to Blackstone for analysis.....and I plan on doing the same after I am done with the GC to see how it does. Then I will decide on what to run in my M for the duration. I already...

Group, We just bought an 06 Ford Focus ZX4 SES with the 2.0L Duratec motor. Wanting to know how I should start with this.... I am tempted to change the oil at 500 miles, then at 2500, 5000, 7500, and 10k. Then start a 10k OCI from that point. Any thoughts? I am planning on using Mobil1 5W20...

I found these at PDI Performance Parts while in Norwalk, OH racing at a private event at Norwalk Raceway Park.... I got the 6 filters for $42 ($7.00 each) I got a filter stash now...a stash of some of the better filters that have been made.

Group, I am preparing to change out the gear oil, and tranny fluid/filter in my wife's 1995 Caprice. It has the L99 motor, and it has 170k miles on the clock. What gear oil would you recommend, and what tranny fluid would you go with as well. It gets driven ~ 50 miles a day, and I would like...

Group, I recently had my timing belt, and water pump replaced. After replacing the parts, the repair shope used DexCool to replace my G-05 coolant. Well, the weather was warm today, and I decided to get the DexCrap out of my car. I also decided to replace radiator hoses. I got 2 gallons of...

Group, As part of my project to install Auto Meter gauges into my 300M, I am replacing my stock trans pan with one modified with a drain plug, and a temperature sender. Even though I only have ~ 10k miles on the ATF+4 and filter in the tranny, I am going to replace the fluid & filter when I...

Group, I am thinking of making the move from Mobil1 5W30 EP to GC 0W30 for my 99 300M w/102k. What I was thinking for an OCI was 10K with filter change at 5K. I know the filter change may not be necessary, however...it would give me piece of mind, and certainly wouldn't hurt the oil. From what...
