Hey folks,

My wagon 2000 uk turbo 1998 S plate, with 139k on the clock is due an oil change.. I can get my hands on multiple quantities of the Mobil 1 Motorsport 15w 50 oil, and wondered what your thoughts are?

Any idea what grade i should go for? Or will this be okay?

The car has an uprated turbo, exhaust, 550 injectors and FMIC..

Any help greatly appreciated..

Cheers

 

i used it all the time , they have now stopped making it though

 

Oh right, we have about 15 bottles of it here - just hope the date of it is okay - Thanks for your help..

 

It was bought in July 2011 so should be fine

 

nice one they replaced it with 10w60 extended life oil.

sounds ideal if you have lots of it there

 

I've been using 15W50 Mobil 1 Motrosport in my MY99 uk2000 since 2001 and have no complaints at all

Have around 60ltrs left in stock now that was produced around 2006.
I will keep using it till it's gone

 

Mobil 15w 50 is poo. 15w 50 Motul or 10w 60 Millers

 

any chance of explaining why its POO ??

 

Compared to the other oils it gets dirty much quicker. Also found that engine sounded more noisy with Mobil 15 50. Lastly a few tuners told me not use it aswell.

 

Any 15W engine oil will have very little initial cold start protection at this time of year and put unnecessary strain on your battery and starter motor at it tries to turn the engine through something resembling treacle.

Better suited to hotter climates!

 

never noticed myself.

actually made 1 of mine quieter than normal.

used both mobil1 and teh lucas race and found NO diff.

a tuner once told me impreza's are crap,i disagree

 

No problem. Its my opinion

Mobil is only good if you want to save money

 

its not any cheaper

was gen asking why you never liked it.

was expecting a better reply than a tuner told me not to

 

Oil is meant to get dirty, thats how it works, by taking contaminates out of the engine (carbon in this case), but its the wrong time of year to run a 15 cold weight oil, you need a 10 or a 5 really.

I rather use chip fat

 

crisp N dry is good

 

Oil always good for a bun fight on the forum!

I'm running 280/270 on a UKMY99 Since 2001 15w/50 Mobil and she is still sweet as.

Last 10 yrs in Mallorca helps though

Frost what frost

 

On a stock car is ok. On a boost engine you can smell that oil burn...

 

I wouldn't put 15w/50 in my lawn mower. It's designed for low tech classic/vintage engines to fill up the void between piston rings and the bore!

 

Okay, so what would you go with / recommend (as it is chilly most of the year here in Shetland)....

 

0w/30, 0w/40 or more widely available, 5w/30, 5w/40, would be more than adequate, unless your using your car in Time Attack during regular trips to Knockhill!

5w/30 is the manufacturers recommendation for a standard WRX, for instance.

 

think i will give the 0w30 and 5w/30 a miss, i reckon my car would fall out with me after a few laps atr knockhill

 

Probably not recommended for circuit racing, you're right. But then again, the oil best suited to racing ain't the best stuff for your daily drive!

What's the answer? Change to oil to something suitable for your track days and then back again for road use? There isn't a product that is fully suitable to do both.

You could buy a 0w/50, 10w/60, but the higher end of the viscosity range wouldn't offer the best protection when pottering about in the cold and snow!

 

yes very true mate.

car doesnt get used as a daily so no big issue for me.

not sure about OP right enough.

cheers

 

The Mobil is a good quality oil, no problem there.

As others have said, 15w is not ideal for cold start in the winter, 5w or 10w is where you want to be.

ALso, check how old the oil is, as the 15w-50 has been discontinued for some time now.

Cheers
