the last few oil changes I've used Quaker State's High RPM synthetic oil. Does anyone know how this oil stacks up to the Mobil-1 brand oils? I would like to be able to use redline oils, but $6.99 a quart is too much for me...

TIA

EDIT: I forgot to mention, its a 2002 WRX with a 4EAT that I use for rally-x (possibly some auto-x this season) for the rally-x I just put the car in 1st and leave it there so the RPMs run pretty high, hence the use of the "high RPM" oil

 

I honestly don't know anyone who uses Quaker State synthetic. I use Mobil 1 because it's readily available at an affordable price.

During rally-x, chances are that the duration of engine high-revving is relatively short compared with what you might experience for a 20-minute lapping session at a road course track day. I think that any name brand synthetic should be sufficient as your engine won't see the type of load from 3rd or 4th gear at full-throttle.

Have you considered a small auxiliary automatic transmission cooler to protect your 4EAT?

No, I havent thought about a small AT cooler, but I'll look into it. In the list of stuff I forgot to mention, I forgot to mention track days, I've already done one at Laguna Seca and want to do more...that ish is addictive

 

I Googled for an independent test of available synthetic motor oils and came up with nothing relevant. Most of the search results pointed to Amsoil's site or distributors. Because of that, I can't view those tests as unbiased.

I use Mobil 1 mainly because I believe that synthetics will be better for our engines under just about any circumstances compared with conventional oils. I do not have any data to back up my opinion, sorry. What might be useful is to visit an SCCA event and speak with the racers who do this for a living or at least many, many weekends out of the year as a hobby. Ask them what lubricants they use in their race cars and then ask them if they use those products because they are sponsored by Red Line (or whoever).

I think that using a name brand, commercially available synthetic motor oil and performing frequent oil and filter changes will give good reliability and long engine life barring mechanical failure (knock on wood).

Read the labels on Quaker State carefully because some of their oils are recycyled.

 

I personally have used mobil 1 synthetic and when i went to red line......night and day. Plus i have noticed that i dont get as much oil burning up with the red line. It is hands down the best oil in my opinion. It is worth every penny.

Start a piggy bank

 

I use Mobil 1 530 because I can get the gallon jugs (4.75 qts.) at walmart for 20 bucks.

 

I know the member who posted was asking specifically about Quaker State synthetic but there is a vendor on the forums who is running a special on 5 quarts of Red Line and a factory oil filter. Red Line oil is pricey but if you really feel the need for it, this might be a good deal.

There must be a reason Porche & Chevy Corvett are suggested to use Mobil1, by their manufacturers. I believe Mercedes does also.
Last I heard, Amsoil, Mobil 1, Redline, & Royal Purple were the only true synthetics.
The others have a different molecular chain.

 

the good mobil 1 stuff is about a buck cheaper than Redline, so if I was going to pay that much, I'd just go the extra $5 and get redline
