I searched and found couple threads on it but non had an good definite answer.. i went to wal-mart and saw mobil 1 came back with the new 15w50.. recommended for turbocharged car so i bought 5 quarts.. has anyone tried this stuff?? i have close to 50k miles and wanting a thicker oil for better protection and summer is going to be hot.. 50 weight oil dont always mean its thicker either.. can anyone give me some feedback on this product? i tried various type of oil and see what works best in chicagos ever changing weather.. i have royal purple 10w30 in my engine right now

 

50? Seems a little heavy. I don't know how the turbo is gonna like that stuff.

 

It aint gonna hurt it. I run 10w 40 RP

I'll proly go 15w 40 next time

 

i run 15w 50 on both mine over the years... even ran it in my eclipse! Its great, but i wouldnt say its a HEAVY oil.. it runs smoother for higher performance vehicles... you wont have a problem... ive ran it 12 months a year in the cold *** winter too here in WI... RUN IT

 

it gives more protection. i use it for over a year. no problem

 

The more miles on your motor the better this is. Reason being as the bearings wear out more clearance between mating points. Little more oil won't hurt at all.

 

thanks guys

 

Pardon the revival but any thoughts on this for fp turbos? There is added zinc supposedly in the 15w 50

 

if its not on fp's oil list, dont run it.

 

Its not even mentioned on their pdf, but the zn and phos contents are much higher than 10w 30 mobil1 normal. Anybody running this on any fp turbo?

 

I also apologize for the thread revival, but it beats creating a new one. For those of you who use this, how do you like it so far? Reasons for choosing?

The numbers are supposedly 1200+1300 PPM which is decent considering the availability and convenience. I made the switch up from 10W-40 not too long ago. TIA!

 

I'd like to know also. I'm at 77k miles and if it's gonna help, I definitely want to use it. Running Mobil1 5-30 now...

 

i currently run it in my evo built motor hta86 no problems smoke or ect my engine builder told me to run it so thats what i run.

 

It would not hurt especially during the hotter times of the year here in SoCal moreso if you are outputting beyond factory power levels.

Glad to hear it! What is your change interval and how does it look then?

FWIW, I am using it in my 3000GT VR-4 @135k miles

 

I run Mobil 1 15w-50 (SM) in my high hp Evo and love it. The newer SN spec has gone down in zinc, phos and moly so I might run a different oil after I run out. My local Walmart stocks the 5qt jugs which are still SM spec but the quarts are SN.

Found these VOA's from BITOG-

VOA of the newer SN 15w-50 oil-


And here's the older SM formula-


Definitely is a difference between the two. I was at Walmart today and I bought up the SM jugs they had in stock.
