oil question

Blackbeauty v601 · July 5th, 2008, 04:22 PM

Ok so i need to know what i should do about my oil a friend of mine told me to run full synthetic ( mobile 1 5w20) but my other buddy told me to put in a blend (valvoline durablend 5w30) As of right now im running 5w20 conventional oil so what do you guys think i should use for my next oil change.... im at 42,000 miles on my car.

Yea synthetic oil is good, both of those are good oil to run in these cars.

04DSGV6 · July 5th, 2008, 05:07 PM

synthetic is the way to go but just so you know mobil 1 technically isn't full synthetic though they do say it is

V6 Stalker · July 5th, 2008, 07:31 PM

ROYAL PURPLE FTMFW!!!! 5w30 btw... since u live in ohio u need the 5 so u won't have cold start proplems. and the 20 stays to thin and doesn't lubricate enough. also the thinner the oil, the more often u have to change it.

Straight from an ASE mechanic --> "The only reason car makers say to use 5w20 is because it allows the vehicle to get 1 to 2 more mpg during testing, but it is way to thin to use for everyday use."

Advance had that deal where u buy 5 quarts of mobil 1 and a filter for 26 bucks, so Mobil 1 5w30 FTW imo

El_Cangri · July 6th, 2008, 12:32 AM

use castrol, mobil1 or royal purple.

I use w.e brand if there is a deal i get it lol but it has to be one of those brands mentioned and synthetic by the way

ItaliStang · July 6th, 2008, 12:49 AM

like they said, mobile 1, royal purple are the best brands....

I use Pennzoil 5w-30, cause I'm a cheap bastard

hell... works fine for me

besides, my grandpa has worked on fords his whole life, and used nothing but pennzoil in his shop...

If it's good enough for his classic t-birds he used to restore... I think it's good enough for a V6 that rarely see's 3k rpms

but if I had the $$ I'd go for royal purple

5w20 has nothing to do with better mpg
it has to do with bearing clearance in the crank, and rods
using 20w50 on a brand new car that needs 5w20 will probably eat up a bearing

5w30 would be fine on a car with those miles even 10w30
the only case i would use such a thick oil or why anyone that races uses a thick oil is to help prevent blow by or so much of it. lots of nitrous guys use thicker oil. my buddy with a h22 accord (n2o) uses it but he also now has a rod knock that gets worse everyday

as for synthetic you dont need it at all. I've seen an oil pump that used Napa cheapo depo oil with 86k miles and the pump was FINE not a bit of sludge. cut open the oil filter, no slugde, nothing on the valve covers, head or in the oil pan. with regularly changing your oil you wont have issues
also on 86k miles factory AIR FILTER, COOLANT and spark plugs

itschristorres8 · July 6th, 2008, 02:44 AM

oh and royal purple is a pile of shit next to amsoil

Mustang RacR94 · July 6th, 2008, 10:03 AM

i wouldnt run valvoline, but run synthetic, royal purple FTW

Mustang RacR94 · July 6th, 2008, 10:04 AM

ive heard alot of bad things come from amsoil, i know a few serious cars that run it, but theres alot of people that wont run it, ask about that in the 4v section. no one there reccomends it at all

HMUSN · July 6th, 2008, 10:06 AM

just get this and you can run whatever you want.

Mustang RacR94 · July 6th, 2008, 10:09 AM

dear mother of god

94v6blkndred · July 6th, 2008, 11:16 AM

haha wow....

and yea im cheap too...i run castrol syntec blend 10w30...i think i got a leak somewhere so i dont wanna run full syn or a thinner weight untill i fix it.

i would have to assume since 5w20 is a lighter, less viscous liquid, and has less fluid density, than say 10w30, that the engine would have to use more effort to churn through it. and since viscosity is just a measure of a standard amount of oil to flow through a standard orifice in a standard amount of time, i would have to again assume a lighter oil would take less effort to be thrown about the inside of the engine. And in todays world, a one or two mpg increase from simply changing oil weight is better than 0 increase. But in all honesty, i could be talking out of my ass again and could be wrong.

castrol gtx 10w-30 here. I wish I could afford royal purple though. autozone was selling 5 qts of valvoline oil w/ an stp oil filter for 14 bucks last time i was there.
