Amsoil 5W-30.

Real synthetic oil.

 

Sounds like a drink.

 

Amsoil is pretty much the best oil there is out there. Just google it and do the research yourself and the facts are there. That's what I use.

 

The "w" rating is waaaaay below 32F. You can have a 0w that's thicker than a 5w at 32F.

 

The problem is you will never see the mileage difference between a 20 and 30wt. We're talking .5mpg in most cases. Just not worth it IMO. Now if I were a manufacturer looking for any .001mpg I could get in a fleet of 1 million cars sold it would be worth it.

 

Do you guys know why you like RP so much? Or is it due to the advertising.

I find it funny that people can post terrible UOAs on it yet the import crowd will continue to pay $9/quart for complete crap.

 

Mobile 1 full syn baby!!! feels so good when i change my oil. so fresh!!!

 

^ yep yep

 

It's because of the propaganda video that Royal Purple made (which can be seen on YouTube). No bias there.

 

Amsoil 0w20. If you use it with the Amsoil filter, nothing is better for your engine

 

hey guys i got a noob question..this is my first car and first oil change for it..its got 70k miles and i live in hawaii..

im thinking of getting mobil1 5w20 full syn. with mobil1 filter..its that okay ?

 

What does the engine cap say? I thought it was 5w-20 (correct me if I'm wrong)

 

make sure you get the correct mobil1 filter, they have different types, just ask the sales person to check which one fits on the TL.

 

You really want to get the Mobil 1-104 filter. Its for the Honda S-2000 & is a bit bigger then the TL stock one.

Fits with no problems at all.

 

HONDA 5-20, 47,500 miles 29 mpg

 

LOL. Amsoil straight 30wt. 32mpg.

 

Mobil 1 5W20 and Mobil1 filter when MID gets to aroun 30% which is around 5.5-6K miles for me.

 

Royal Purple 5w 20 ^^

The local Honda Dealership also uses RP in their cars. 40 bucks for an oil change 2-3x a year is fine for me, i don't think it matters what oil you use, but how often you change it.

 

^ ^ ^ ^ ^ ^ ^ I would sue my dealer if they put that crap in my car.

 

^^ Whats wrong with RP? I am thinking of trying it on my next oil change.

 

The biggest problem is RP has posted some bad UOAs (Used Oil Analysis) results, especially in higher powered cars that are run hard. That combined with the high price makes it a total rip off.

The HT/HS (high temp, high sheer)values are very low. These values are just as important and some can argue more important than viscosity values. This test demonstrates how the oil will behave and protect in real world high stress and high temp conditions in a bearing. You need at least a 2.6 to keep the engine from a premature death. From memory, the thinner RP is right around that value. I personally like it >3.2. My current 30wt oil is a 3.5.

To over simplify, when put under stress, the oil will temporarily sheer to a lower viscosity and the ht/hs number reflects that.

Redline is a great oil and their 20wt oils have a very high HT/HS, higher than most 30wts. This would give you the thin viscosity and protection needed for a daily driver that's run hard occasionally. In other words, it's a 20wt when it enters the bearing and remains a 20wt under stress.


I think RP does have a valid place for those that have a large financial backing and don't mind sacrificing some wear for that extra 1-5hp. But for a daily driver car like the TL that you expect to run well past 100,000 miles I wouldn't use it. I'm not saying it won't go 100,000 miles on RP because I'm certain it will, but you won't be getting the best wear protection as you could with other oils.

 

Mobile 1 5w30

 

Mobil 1 5W20 and Mobil1 filter. My TL only has 20k miles on it , so I change my oil every 5 - 6k or every 6 months, whichever comes 1st.
