Default Mobile 1 or Another?

Is Mobile 1 the best synthetic oil to go with in a 2002 WRX? If money was not an issue what is the best engine oil to use and how often should we change it. Will I actually feel/notice a performance difference between synthetic and regular oil? Is there a real difference between regular and Subaru oil filters?Thanks.

I use Mobil 1 in my 98 RS. I only use it because I trust the name though. I'd be interested to know as well if this is the best oil for me to run.

Default Yo yo yo ...

I got my oil changes yesterday for the first time ( 3003 miles ) and I had a dicussion with the mechanics about synthetic vs. regular. He tried to make a point and just put synthetic in my WRX for free ... not Mobile 1 though. I'll drive around for the next few thousand miles or so then so to Mobile 1 and see if there's any difference. I don't mind spending the money but there BETTER be a real performance difference.

Exclamation Be careful, be very careful...

The moderators of this forum may 86 you for mentioning a brand name of a product used in routine service and maintenance. It's also dangerous to ask about the "peformance" of a particular product that has to do w/ routine service and or maintenance. They're watching us out there...

Speaking of children, "your" should be spelled "you're", which is a contraction for "you are". Sorry for being a nitpick

There is a difference from mineral based to synthetic oil. Synthetics create less internal wear, and lower operating temperature. You should also see a slight improvement in fuel mileage and hp (maybe 1-2).

There are some oils that are better than Mobil 1. Amsoil, Redline and Royal Purple to name some.

One more thing. The oil filter is very important and often overlooked. The OEM filters are good. Purolator is ok. The premium oil filters such as K&N, Mobil 1, Amsoil are an upgrade from the OEM.

Stay away from Fram. They are the worse piece of crap filters made. BTW, Fram manufactures filters and sells them under many brand names, so I suggest that you stick with one of the filters listed above.

Can you support this claim? Other than saying that AMSOIL has more ZDP....

Do years of racing and rebuilding motors after every season qualify?

Seriously though, Mobil 1 synthetics are pretty good. Dodge Vipers, newer Corvettes, and newer Porsches come from the factory prefilled with Mobil 1. My Typhoon even came from the factory prefilled with Mobil 1 10w-30. If Mobil 1 is good enough for the 450 hp Viper and the 405 hp Corvette Z06, then Mobil 1 will be good enough for your WRX.

Notorious ~~ Not really. I've seen some "professionals" on infomercials for various car products that I wouldn't even want in my TRUNK.

Very funny! But really, I've seen the inside of motors after a full season of abuse, and it is amazing to see find almost no wear.

For those that use Mobil 1, don't get me wrong; I think it is very good. It's just that I think that for the same price, others are better.

Default Weird ...

I never knew the actual oil filter would make a difference ... can I "really" tell by driving the car? I'll probably go with Mobile 1, Amsoil, Redline, or Royal Purple during my next oil change and also a nice filter ( assuming that even makes a difference ). I had my oil changed at FireStone since I trust them and also needed to barrow their lift ... so much easier to install KartBoy bushings when the car in above us standing. The installed a FireStone oil filter but I can't tell a difference. I guess I'm still relatively new to all this ... I guess I'll live and learn.

The oil filter doesn't make a difference in performance (hp), but there is a big difference from one filter to another in what particles are trapped and kept from going back into your motor. It has to do with the actual type and amount of filtering media used in the filter, and with the design of the filter. (anti-flowback valve) Cheap filters can also have weak casings, crappy internal cores and bad seams. IMHO, the better filters are worth the extra dollar.

Default Humm ...

I didn't know that ... I thought an oil filter was an oil filter but I do learn something everyday. Where can I pickup highend oil filters for my 2002 WRX? I heard Costo was cheaper for Mobile 1 5W30, can I also get them there or is there a place where I can get everything all together? Is there somewhere on the NET that I can order from which would be alot cheaper? Thanks.

Took me awhile to find it but this is an interesting page on oil filters and their construction. I personally have always used NAPA (Wix) filters.

If you're having a problem finding one of the better filters, use the OEM. For the best price, just buy it from one of the dealers that sell it at discount or from Sugar (I-Club vendor).

Default Funny ...

I went by Troncolli today to pickup some touch-up paint for my red WRX. I asked for Lisa ( Sugar ) and she was standing right there ... I found that kinda ammusing since I said something like ... umm I heard around you on I-Club ... it was cool though.

I am curious as to why I never hear mention of Castrol Syntec
in discussions of synth oil. Is there something inferior with it
versus Mobil1. I have used Syntec 5-50 with no issues.

Oil and filters from different companies are usually make a little differently from each other. Other labels are just that labels on the same product.

For instance, the Subaru OEM oil filter is the Puralator oil filter.

Synthetic oils like Mobil 1 and Redline are also formulated differently for different purposes. Mobil 1 is formulated to behave in a manner close to that of regular dino oils. It is still far better than regular dino oil, but it contains all the same additives and detergents that go into regular dino oil. Redline oils have less detergents and more of the other additives in different ratios than Mobil 1. Both are far superior to regular dino oil, but are setup with different purposes in mind.

If you are still not sure, write to both companies and ask their technical staff about the differences.
