Currently I have in M1 5W-30 and a purolator pureone filter which I put in at 500mi.
I was thinking of probably changing it around 5k (OK?). When I change it I was thinking of what to use. I recently noticed my Advanced autoparts started carrying redline engine oil.
I have searched the forums and I have heard redline is superior to M1.
I can get 5W-20 or 5W-30 Redline at my store. Which would be better for my application? and Could I run 10K intervals with Redline and be safe w/ mabey a filter change at 5k intervals? What is a good filter to be used with Redline? I usually use purolator filters.
Thanks, sorry for the long post, but wanted to include all the details
I've been running RL 5W30 in my slightly modified 2003 Mutstang GT, and aside from all the propaganda regarding the effectivness of the 20 weight oils, I made a conscious decision. The decision is that I would stay with a tried and true oil viscocity and a top notch oil.
We also have a 97 F-150 Lariat w/ over 210,000 miles, and we've been using Mobil 1 10W30. The engine configuration is slightly different; hence the 10W30.
One thing you need to know is that Red Line D4 ATF (Mercon V) is not good for your T-3650 tranny. The synchro rings are carbon fiber, and RL makes these rings brittle. I know it's wierd, but a lot of teh Mustang folks on
www.mustangworld.com are using GM Synchromesh manual transmission fluid in their T-3650 trannys. GM Synchromesh takes the characteristic 1-2 shift grind out of the picture completely. Don't use Red Line in the T-3650 tranny.
As far as engine oil change interval, you don't want to mess with extended change intervals while on warranty. Change the Red Line out at 5,000 mile intervals as per manufacturer. After that time, you may go from 10,000-18,000 miles on Red Line w/ no problem.
Make sure you use a Motorcraft FL-820S filter; otherwise, Ford can blame engine failure on the oil filter.
Take my advice at face value, but do some research on your own. Congrats. on the Stang. They are an exceptional vehcile.
