Hey that car at 440,000 miles should have run better then
14.15@100.99 It should be broke in by now.
Hey would grandma like you taking her car to the drag strip? LOL

Have you thought about running the mark 8 on MS?
Seems like a cool deal for those that are severly DIY inclined.

Its hard to debate with a guy that has that many miles on a Mark VIII.
95 Lincoln Mark 8
400,404 miles
95 Lincoln Mark 8
400,404 miles
my original 95 engine lasted until 360,000 miles and it chunked a secondary cam chain tensioner (I dont consider that an oil related failure)
it ran for about 15K afterwards while I found a low mile 93 engine to replace it with.
When we pulled the 360,000 mile motor apart it still had the crosshatch in the cylinder walls.
I always used Mobil 1
I put 6000 passes on the car at the dragstrip over the course of 9 years
6000 passes is roughly 1150 miles of WOT..(lol)

Another e mail from shell oil But there getting in areas I don't understand? any way maybe you can.
Danny,
You may indeed see an improvement in mileage with synthetic vs. mineral oil. It would probably be on the order of about 1-2% and so may be hard to measure.
Concerning the oil flow, the 40 weight is more viscous by about 1/3 to 1/2, (Example at 100 degrees Centigrade: Typical 15.5 centistokes for Rotella T 15W40 vs. 10.6 centistokes for Formula Shell 10W30) so it may build a higher level in the valve area in order to drain. I do not know if this would be significant, it would depend on how small the drain back spaces are. For the same reason, the 40 weight will require additional oil pressure to create the same flow.

Going in the other direction, what do you think about these claims that 0W-20 can be used in place of 5W-20 in our cars:
http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_0W-20.aspx
"Mobil 1 0W-20 Advanced Fuel Economy outperforms conventional oils and meets or exceeds warranty requirements for many Ford, Honda, Toyota, Mazda, Mitsubishi and Chrysler vehicles. "
"It is specifically designed for applications requiring an SAE 5W-20 oil such as most Fords, Hondas and 2005 Chryslers."

I never heard of it till yesterday. Have you tried it? But i never heard of a 5W-20 either.I guess I'm been setting still why the world passes me by.
Why not just use a straight weight like a 25W non detergent then ? Wouldn't That be a 20 weigh detergent oil?

everything ive been tought about oil coming from working at valvoline going to school and talkin with a lot of mechanics is use what the factory recommends its the winter. in the summer you can run something a little thicker like 5/20 in winter and 5/30 in summer. never change what type of oil you use just pick one and stick with it. never switch back and forth between conventional and synthetic. even though you use the same weight the molecules are smaller in synthetic and cause find places to leak. i thought the rotella 15w40 was for diesel trucks,

i have thought about it. most of the bugs are starting to get worked out of the EDIS setups. but i will wait until i have a decent bit of mods before i even start to really look into it.
for people that dont know what megasquirt is, its a FULL standalone EMS that you can install to completly replace your stock ecu, for only $200. it really is the best thing since sliced bread.

Just from past experience 5w20 the 5 is important for cold start up it flows a lot quicker than say a 15w40 when most engine wear occurs 0w20 is even better but actually is to thick at start up. The larger number only has to be able to keep proper oil pressure at operating temperature,any larger number only consumes more fuel and puts more wear on oil pump and related parts along with less flow.I have a 7.3 powerstroke that gets better mileage and better oil analysis results with 5w40 mobil1 delvac synthetic than with rotella 15w40 although rotella is an excellent product for the price.Also when Ford started using automatic trans fluid in their F350 5 speed manuals I had a shop unknowingly replace it with a 90w gear oil.Trans was toast in less than 30 miles.Just because a heavier oil quiets a tick or a knock does not mean it is good for the rest of the motor.As the knock gets worse would you eventually use 120w gear oil.Just some common sense experience from an old timer with an open mind.

Makes sense to me.
And yes Monday I'm gonna change the oil back. I lost 1 mile per gallon with the heaver oil. So I figure if the car has to use more gas to do the same job something isn't right.So you and the Mark showed me.I used to use the Mobil 1 0W-30 in my trucks (light duty) with great results. I was also making winter trips to the Canadian border. Now that I mostly stay in Tennessee or fly home for Christmas, I have stuck with the 5W oils. For no other reason then I have had a hard time finding anyone that will special order the 0W oils for me, nobody stocks it anymore...

For the Record, I was'nt asking a question about the oil Bryan. Just pointing out that my Powerstroke likes Rotella ALOT more than my 94 VIII would.
Not to change topic AGAIN...... but most modern diesels are running below 20.
My Stroke is around 17 somethin IIRC. Now the older IDI 6.9-7.3 Fords were running greater than 20, along with the GM 6.2 and 6.5's.
Thank GOD those days are over.
