I'm sure you've seen plenty come out of the drain... with conventional oil. ;)

I don't really recommend the 25k interval unless you're using oil analysis. But the 3k interval is unnecessary. Most manuals recommend a 7500 mile oil change under normal conditions.

Yeah, but what they consider to be normal conditions is grandma driving. No offense to grandmas.

In Europe, I believe the standard is 9k.

Kilometers or miles? ;)

Amsoil is awesome. A little expensive at $8/qt, but with the hi-flow amsoil filter you can go 25,000 miles or 1 year (whatever comes first). I couldn't find the filter so I just went with a Honda OEM (Fvck fram and their chep cardboard filters)

Amsoil XL-7500 is 7,500 miles or 6 mo whatever comes first. This is the option I'd reccomend to most people. The only reason I got the regular amsoil was NAPA was out of the 5W-30 for the XL7500.

As far as other synthetics such as Mobil One, they will do a better job of keeping your vehicle well lubricated. Sometimes you can see increase gas mileage too.
North American Honda filters aren't much better.

allrighty then. Everything I've read says to use 5W winter 10W summer. Are you sure about this?

I personally don't buy AMSOIL'S claims. Royal Purple for me and changed every 2000.

It's fine. It's OEM and it's not made of cardboard bullsh1t like fram

most honda OEM filters are frams. haha. and if you're not doing oil analysis every 5000 miles at least, it's not a good idea going 25,000 miles.

I live in NJ

5W-30.

What would be the main difference betwene that and 10w-30 besides temperature thingie :)
Nothing. The xW is a measure of it's cold temperature viscosity.

At temperature, they are both 30 weight oils.


Cool then 5w-30 it is with a Denso (JDM) filter.
For some reason the JDM denso filters are better made than the USDM ones. well atleast for my car anyways.
w3rd to denso..JDM denso radito0r r0x0rs j00r b0x0rs

wtf? my denso radiator had plastic at the top and bottom and cracked, the replacement i got had nice metal on the top and bottom so what does that say? :p

25,000 miles a year? You'd have to be out of your mind. I'm and ASE tech and have seen all kinds of things come out of drain plugs after 5,000 miles...

And why is the XL7500 Series the only one to have API Certification? You know the starburst symbol on the side of all oil containers? That's what all automakers recommend in their manuals. The oil that Amsoil recommends for the 25K interval doesn't rate!

Heres the list: API Website. Click on the license number to the right.

they try to explain that on the amsoil website.

you could buy the cheapest oil and filter you can buy and it would last double that.

you're wasting your money and are a fool. :)

That is your opinion. My opinion is that a 10k motor shouldn't be left to chance.

Maybe you should read
this pertaining to the honda filters and stop being such a moron bandwagoner with the fram bashing. Not that I love fram, but it sounds like you're basically putting on the same filter unless you're ordering them from japan (hmmm, doubt that). On the other hand, you can keep believing that "It's fine" with the ignorance that it's honda and therefore the best.

I can tell you from personal experience that some of the manufacturers (Honda) won't warranty an engine unless it has an OEM filter on it. Now, of course this goes against federal law which states that you can have your car serviced somewhere other than the dealer and not void the warranty. I'm just saying that a lot of the time it comes down to a judgement call (by the dealership), if the engine has been maintained properly. They can say it's been too long since the last oil change, or that the oil is sludged or whatever. Whatever they need to say to get out of it. In my line of work I've seen it dozens of times. So my advice is that if your car is still under warranty, spend a little more and buy OEM filters - regardless of what you think the quality is.

Simple rule I go by...

Oil I use Mobil or Mobil1. Cost is in the middle compared to others, and can be found anywhere.

Filter I use STP or Tech2000. Both of them are the same. Tech200 can be found at walmart and STP at autozone.

not really, considering that I bought a CDM one that's still flows better than a FRAM.

Kinda strong there, but I have to agree ... unless it is a taxi cab or an inner city police cruiser, sitting at idle for hours at a time.

As for the whole 10W in the summer and 5W in the winter, it doesen't matter. Like I said, think about it. The only difference between 10W-30 and 5W-30 is the cold viscosity.

Sure, you can use 10W in the summer.. because, well.. it's summer. Theoretically, it's warm enough that the oil is pretty damn fluid. But the fact remains that they are both 30 weight oils at operating temperature.

5W-30 is considered "all season". It doesen't matter.

If your car doesn't have oil leaks it is nice

Your oil pump works a little less hard to pump the synthetic because of its flow characteristics-engine will run a bit smoother.

I used redline synthetic oil in engine and tranny, it's very good stuff.

Careful with the redline racing oils. Some of their formulations don't have very high detergency and other additives because it's assumed they aren't going to be staying in the engine long.

Really, you can never be too conservative with oil changes. I agree that 2k is VERY conservative, but if that's what makes him feel good.. then it's worth it to him.
 

Synthetic is good for an engine and it'll increase your oil change intervals, but it's just as important to use a quality oil filter. Don't put Mobil 1 in there with a Fram filter - it won't be doing much for you.

But yeah, if I didn't have time to change my oil every 3,000 mi., I'd definitely use synthetic.

I cannot stress this enough.

The best oil on the planet is rendered useless if your air, and most importantly.. oil filters aren't doing their jobs..

my dad just put in 10w-30 mobil 1, and some filter (not sure what) in our avalanche. he changes his oil about every 3 weeks (yes, that is 3 weeks, or 3000 miles!!!!!!) i dont know if hes seen an increase in MPG but he says he is just doing it to keep the engine better lubricated, its the first car hes used synthetic in, our other car, a 99' tahoe had 97,000 miles on it when he sold it a month ago (shows how many miles he puts on in a year). nothing was wrong with it. 10w-30 all year round i believe, and we live in northeast ohio. he always lets his car warm up before he starts driving though to let the oil get around.

New Toyota Tacoma TRD. Mobil 1 synth oil and Mobil 1 filter every 5000 miles. It's easy to remember, 5K, 10K, 15K, etc.

Sorry to break this to you, but your father is throwing away money and shortening the life of his engine at the same time. The days when engines required 3K oil changes are long gone - along with carburators. He is literally throwing his money out the window by doing it at 3K instead of 5K and 7.5K especially if he's using synthetic.

Also, letting your vehicle warm up actually increases engine wear as it take much longer for internal componants to warm up when the engine is idling, rather than just driving away. This increases engine wear significantly. Don't worry, your engine has full oil pressure within seconds of start up, then you should just drive away easy. This is what all the manufacturers recommend now.
