No way, I have only ever used Mobile1 and just switched to RP synthetic and it's great. My car doesn't leak a bit of oil and I'm at 123K miles. I also use Mobile1 in my tranny.5w30 not synthetic. CONVENTIONAL. Everything i have read on this sight says not to use synthetic in the SVT I'm pretty sure anyway. I have been using Quaker State 5w30 in mine and i am very pleased. As for the tranny the poll leads with Royal Purple Syncromax or Syncromesh not sure on the name but it leads by a lot.

The SVTF takes 5W30.I have been using 5w20.
I don't think you read that on this site...CONVENTIONAL. Everything i have read on this sight says not to use synthetic in the SVT I'm pretty sure anyway.
^^^Correction.The manual specifically states that full synthetic fluids were used for the break-in period.
There are no synthetic fluids or break-in fluids in your SVT Focus engine when it leaves the factory.
Note that SVT does not make recommendations about the use of synthetic oils in your engine.
Should you decide to use synthetic engine oil, we recommend you allow 4,000 to 6,000 miles (6,500 km to 9,600 km) in order to assure complete break-in before switching to synthetic oil.
You are correct. My fingers were faster than my brain. I will edit accordingly.^^^Correction.
It's just the opposite...go look at that scan I posted.
what are you smoking!5w30 not synthetic. CONVENTIONAL. Everything i have read on this sight says not to use synthetic in the SVT I'm pretty sure anyway.
