YouTube Is Synthetic Motor Oil Better For Your Car?

Pretty cool video. Very informative. Demonstration towards the end.

that cold used conventional sure flows like shiiiit.

i commented on youtube and hope he gives it a response, i'm wondering if the narrower range means anything. i don't know if it's myth or truth but picked up that a narrower range meant it would stand up to temp abuse better.

brz says 0w20 or 5w30. i put 10w30 in it thinking it would have higher pressure and hold up to high temps moar bettar.

before oil cooler on track, i was hitting 280f. with a coolant based one, i'm 250-260f. pressure at 7000 rpms is 60 w/10w30.

sent some in to blackstone labs after a bunch of track days and on e85 and they said it looked good.



the only direct data point i've been able to compare it to is another guy's frs at different temps and pressures using redline - i have much higher pressure with the amsoil.

That's pretty cool, good info to back up my oil choice on all my turds

is apparently not the bestest?!

Very interesting video. Most informative for me was the viscosity of the 15/40 used oil. That's some nasty stuff!

That's awesome. Reminder to never use the cheap Walmart junk.

Used conventional oil at that, non-synthetic.

not the best if your application is racing really cold oil with gravity, i guess - the only real conclusion i'd draw from this is that royal purple is not that impressive. which no one should have ever believed in the first place, since it's competitive differentiatior appears to be "this stuff is fucking purple, maaaan"

There really are only 2 actual synthetic oils, there's a whole discussion about this on other forums. Nobody around here needs to focus on any of this as nobody runs extreme temperatures or driving.

His graphs are cute but the actual difference between the two over an oil change interval is like nothing. You could easily race your car on conventional oil as you can with synthetic.

Also, why compare 15w40 conventional new/old vs 5w30 synthetic new/old? To show the DRASTIC difference between synthetic and conventional? Even though they're not the same to begin with? Am I missing something?

btw i really like this guy's channel. there is also kyleengineers who is really good too. he is an aero engineer. he has an 86, dunno what this guy has. cool to see him use aftermarket cars for my car as examples when he describes some stuff though.

M1 always, if I remember there was quite a bit of amsoil over the years

reminds me, [MENTION=340]Eagle[/MENTION] quickpay me for that 5w30

 

[Primalzer]

I've run a couple of times...but it's just too expensive. I'm sure it's fine oil, but I can get M1 at a 1/3 of the price, and it seems to perform just as good

I use bacon oil

Long read. But so worth it. Love Bob is the oil guy.

And people wonder why I'll prime the engine by holding the gas pedal in my ST down on cold days. They think something is wrong with the car, but its really me just keeping the engine at lower revs to get the oil to move around better.

Plus overnight, the oil tends to drain back away from the Turbo. So the 10 seconds of cranking helps to get some oil up there before the wheel actually spins with exhaust gases.

I only run synthetic in all my cars. The GTA is running 5w-30 Mobil 1 right now. But I need to switch over to a high zinc oil. I've heard its better for engines with higher valve spring pressures because the zinc forms layer on the came lobes.
