so what Synthetic oil to use?

[AV6NHBP6SPD]

ok since i use amsoil and Paul and some other guys said that it would need to be changed more offten then 10K. what would be good replacement full synthetic oil?
i paid about $55 for oil and synthetic filter from Amsoil and that's with my 20% discount that i had

so whats good? i dont think mobile 1 is good

i guess still want to stay with 0W-30 from Pauls recommendation a while back

I always thought Mobile 1 was good that's why I've always used M1 5w-30. You can get a 5qt jug and pick up a filter for around $25 at Walmart.

5W-30 is not full synthetic

[Abailey4]

Oh ok. So that's why some people are using the 0w-30?

[AV6NHBP6SPD]

^^yes. according to Paul thats full synthetic and not the blend

[Abailey4]

Gotcha.

Pennsoil Platinum 5w30 is a really good oil.   Better than mobil 1 5w30, although there are a lot of oils that are.

GRP III oils are considered synthetic today.  PP uses GRPIII base with esters (GRP V) while Mobil 1 uses GRP III base with PAO's.  The additive pack is what distinguishes a good oil from a great one.

What's PAO's?

I just changed mine from Mobil 1 5W20 full synthetic to Valvoline SynPower 5W20 full synthetic. I heard Valvoline is kick ass stuff

[InFuMoUs]

I've been using Pennsoil Platinum 5w-20 in the winter and 5w-30 during the summer. After my supply is done, I'm gonna stick with 5w-20. I'm waiting on my next oil change to get this oil analyzed to see how long I can go with this stuff.

i use to put valvoline syn on my car then switch to mobil 1 syn, the car felt smoother

[cna]

Right now am using mobil 1 synthetic but am thinking of going back to Castro synthetic

i guess ill just stay with amsoil with 5k change, unless i find something better and based on results i get from tests

What's PAO's?

PAO's are what used to be called full synthetic.  3 or 4 years ago however, castrol realeased a Group III oil that whas highly purified and advertized it as full synthetic.  Mobil sued them and subsequently lost and soon it was the the properties of the oil, not the base stock that was considered the definition of synthetic, although you'll never find a synthetic with group II oils.  Subsequently everyone, including Mobil 1, switched to at least partial group III oils.

 It's a bit out of date, but for the most part still accurate.

Hears what they say about PAO's

One process for making synthetic base oils is to start with a chemical called an olefin, and make new molecules by attaching them to each other in long chains, hence "poly." The primary advantage of Poly-Alpha-Olefin "PAO" base oil is that all the molecules in the base oil are pretty much identical, so it's easy to get the base oil to behave exactly as you like. PAOs are called Group IV base oils.

Amsoil is still among the best oil you can buy.  Pensoil platinum is popular becasue it is 95% as good for 1/2 the price, and for some people cars, actually better than Amsoil.  That being said, the honda K24 engines (along with the 2.2L GM ecotec) are the two slowest wearing engines you can buy with any oil.  The J30 isn't as good but still doesn't wear super fast.  Unless you live in antartica, or the north pole, there really isn't any point in running super expensive amsoil, when Pensoil Platinum and Valvoline SynPower have just as good or better wear numbers, but not quite as good extreme (-50F and below) cold weather performance.  If your going to run amsoil, at least do yourself a favor and get it analized as you'll probably find you can go 6-15000 miles on one change.  PP and SynPwr are usually only good for 6-12000 miles, depending on your driving styles, and motor.  The J30 suffers from fuel dilution though, so you probably won't get more than 8-9000 miles per change under best case consitions with any oil.
