Hey guys,
I was at the car part store buying some mobil1 synthetic and a mobil1 oil filter. The guy was telling me that numerous tests have been done indicating that amsoil is a better quality oil that is more protective, lasts longer, etc compared to mobil1 (even though its more expensive). (i dont wanna start a debate here on how long it can stay in, I change the oil/filter every 5K)

He then was telling me that he believes that the K&N OIL filters are superior to any other filters, including mobil1. Again, more expensive, but what do you guys know/think? Is the amsoil really a better oil (marginally or not), and is the k&n oil filter superior to the mobil1 (again, marginally or not).

K&N Oil Filter: http://www.knfilters.com/search/prod...x?Prod=HP-1003


Also, is it not recommended to mix mobil1 oil with k&n oil filters? Or amsoil oil with mobil1 filter? (basically just mixing brands)

 

What I'm gonna be doing is using Amsoil (it's 100% synthetic, not based off of fossil-fuel oil like Mobil One is. My shipment of Amsoil is comin tomorrow :D. Expensive stuff though - $85 shipped for a case of 12 quarts. That's about $7 a quart.

I'm also using the TRD Oil filters - i don't see there being a problem with 'em.

 

It's not THAT much more than mobil1, I pay $6 a quart for mobil1 at walmart. But still, its not cheap.

Now what about that K&N oil filter, any reviews?

 

I like their interval maintenance!

SERVICE LIFE
AMSOIL Synthetic 5W-30 Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline fueled vehicles as follows:

• Normal Service(3) – Up to 25,000 miles or one year, whichever comes first.

• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first.

• Replace AMSOIL Ea oil filter at the time of oil change up to 25,000 miles or one year, whichever comes first (other brands at standard OEM* intervals).

 

Yea, those intervals are in fact crazy, I don't know if I would do that however, the oil really does get dirty after a while.

What about the K&N oil filters, any reviews?

 

amsoil is definately the best, couldn't tell you about filters though...

 

im running amsoil now. definitely a nice oil. i'd run mobil1 in my car with mobil1 filters for 40k miles in my old tc. worked great. but i think this amsoil is better. im still using mobil1 filtering though.

 

So what i'm hearing confirms what i've been told, that although amsoil is a bit more expensive, its the best stuff out there.

No reviews on the K&N oil filters though yet...I know mobil1 is good and I know that the amsoil filters are good too, but what about the K&N, its a brand I trust and the look heavy duty, but i've not heard anything good or bad

 

(amsoil oil filters are way too expensive compared to the other 2. K&N coming in 2nd place and the mobil 1 being the cheapest)

 

I'll be running amsoil for 10k miles between changes. I'll be changing my oil filter every 5k miles though... maybe 3k depending on how bad it is.

I dunno about K&N filters. I think they're better at making air filters

Sticking with the TRD Filters here.

 

Have you compared the TRD to the mobil 1 oil filter at all krdshrk? I've never had my hands on a TRD so I have NO idea of the quality vs mobil1 (which is what I use now)

 

The K&N oil filter is a Mobil 1 oil filter with a nut welded onto the bottom, so you can remove the filter with a simple wrench. Internally, they are absolutely identical.

I spend the extra buck and buy the K&N, because that nut on the bottom is more than worth the extra buck it adds to the pricetag.

 

Awesome, that's what i was looking for. Thanks dr. isotope!
