measured oil amount

(Click here to view the original thread with full colors/images)

Has anyone measured the exact amount of oil they put into there mark for the best performance results.

Posted by: 98LSC32V

I usually put in 6.5 quarts, which puts it right at the full line.

Use the dip stick, thats what it is for! You will not gain or lose performance based on a half quart of oil. Some say they take 6.5 quarts, some take no more than 6.

i dance right around 6qts, mid of the stick.
on a side note my last change i tried 5w20 (ford recommends it now for gas millage gains, so they say) but i went to the drag strip a few days later, and i dropped a tenth. IM NOT SAYING IT WAS DEFIANTLY THE OIL but i haven't made any performance mods and i used to hit a 15.2, and with the 5w20 i hit 15.1's consistently. dont flame or bitch, im just saying it might be worth a shot

The thinner the oil the less drag on the engine. I don't think it makes that much of a difference going from 5w-30 to 5w-20 but if you used a 10w-40 and go to 5w-20 the difference will definitely be noticeable. I have Amsoil 0w-20 in my 98 LSC right now.

are you woried about the amount of rotating mass or windage you should be able to get a crank scraper for around $80

Posted by: chickenviii

i wasnt worried about it, just saying.
i tried 5w20 cuz its the same price as 5w30 at work, and when i went to the track, i beat my best time
and removing a oil pan on there arnt fun

5w20 is the same price as 5w30 at your work?

5w30 is almost double over here.

why is that?

Posted by: MYTURN

for all out racing the most horsepower would be so low that at the end of the quarter mile your pressure would go to zero than u shut it down.lol that could be 1.5-2.5 quarts.it would be worth 20plus horsepower of windage but may cause you to get the dumbass award of the year too.

I add 6.5 because my lincoln thinks its a Harley Davidson. It likes to mark it territory!

Posted by: turborich

I use my dipstick like the owners manual says to, To reach the full mark I use 6 3/4 quarts.

Posted by: Goddard-MarkVIII

Well I figured different types of oil amounts would affect pressure. Not sure if this would change speed or horse power.

Posted by: Markviiiedrea

as far as 1/4 mile times you would have better luck taking the side mirrors off.

Without going too far off topic, what do you guys think of 20w50 synthetic blend? Used it in my old 4banger and I swear it saved that engine from destruction...Just curious what you guys think though...

Posted by: 98LSC32V

I would not use anything heavier than Mobil 1 0w-40 in the 4.6 DOHC.

That heavier weight oil would make a good cushion for a tired motor but then again the motor has to work hard to push through it especially when cold.
