[batmobile2000]

Royal Purple 5W 30 and K & N filter every 3000 miles.

[tbojbob]

was usin' RP 10w30 but I think I've found a small stash of GC 0w30 so I may change my RP habit...........

[CamTom12]

I use Castrol GTX 5W-30, every 2500 or so miles. I'd stay away from the truck filter, Bawls... My buddy Bain just drained his crankcase all over the highway a couple of weekends ago because he bottomed out and broke his oil filter...

[josh99ta]

It's certainly a risk Cam, but the extra capacity doesn't hurt. Just have to be careful. FWIW, I usually run a longer filter (Mobil 1 M1-206) but I bottomed out once and it was enough to break the seal on the filter and leak oil, so now I run the regular filter (Mobil 1 M1-106 I think it is). I've also always ran Mobil 1 10W-30.

FWIW, the next oil change I'm switching to Amsoil's 5W-40 euro formula. Formulated to be good for 1 year or 15,000 miles, and I'll run an Amsoil filter as well. It will actually save me money in the long run as I drive less than 15,000 miles a year. I'm looking at one $65 oil change as opposed to two $40 oil changes a year.

[Chris 96 WS6]

I'm about to start running Royal Purple, since Mobil 1 has gone up so much there's very little price difference now. Plus its available at Pep Boys 2 miles from my house.

[4348rd]

castrol ,syn

[LS1Insyde]

amsoil syntec 5w-30

[contraststriker]

I think royal purple performed pretty badly according to an independent testing site I just surfed the other day. AMSOIL = badass though.

[99TAW6CONVERTIBLE]

Q-State 10w30 fram pro oil filter.

I dont like syn-oil.

[mach83]

Mobil 1 5w 30 every 5k. Did use Fram oil filter. moved to mobil oil filter. Oil pressure is pretty high. anyone else have high oil pressure?

[five7kid]

Okay, I don't have a 4th gen, but when I saw the topic line, I couldn't resist.

Just out of curiosity, where are you guys getting this "AMSOIL Syntec(h)" stuff? "Syntec" is a Castrol name.

Anyway, I've been using various AMSOIL products since 1983. In the Camaro, I'm using the 10W-30 Synthetic (as well as in the other passenger cars in the family fleet). In the '57, Series 3000 5W-30 HDD Synthetic (and in the horse trailer tow van). And AMSOIL oil and air filters in all, along with ATF and gear lube and grease. All on one-year or 25,000 mile oil/filter change intervals, with an oil filter change at the half-way point.

For the record, AMSOIL European formula is 5W-40. The 0W-40 is a motorcycle oil. http://www.amsoil.com/products/motoroils/index.aspx

[02lilredSS]

Mobil 1 Synthetic 10w30

I use Mobil 7500 5W20. But I am thinking of going back to Pennzoil 5W20, its almost as good and is cheaper while its also a semisynthetic. I use either WIX filters or a NAPA filter...which is made by WIX. -Tim

[Go Faster]

Mobil 1 5W30

[oldgregg]

Which ever synthetic is on sale, usually M1 or Syntec.

To me synthetic is synthetic, no matter who makes it.

[Phoenix57]

the thing is that Mobil 1 is full synthetic. Castrol Syntec(except for GC), is actually really refined dino oil/synth mix

[Fenster]

I'm about to start running Royal Purple, since Mobil 1 has gone up so much there's very little price difference now. Plus its available at Pep Boys 2 miles from my house.

Exactly. I am swapping the SS over to Royal Purple as soon as this oil change is up. Going to swap out all the other possible fluids as well to Royal Purple.

I've got some SDF filters to use up. After I start getting the new Eo filters, I'll go the the 1 yr/25k miles interval.

[oldgregg]

Castrol Syntec(except for GC), is actually really refined dino oil/synth mixThat would be Syntec blend your thinking of.

Syntec blend sheet (http://www.castrol.com/liveassets/bp_internet/castrol/castrol_usa/STAGING/local_assets/downloads/p,q/pds_syntec_blend_usa.pdf)

And what is GC??

[LiquidFire350]

And what is GC??
im not sure, but id guess its the German Castrol blend

NO... pennzoil is the worst... blah...

i have yet to change the oil in my car... it has about 1000 miles on the new motor... so what would you guys reccomend that is avaiable around here?(Casper, Wyoming) I dont want to have to order oil. lol

I think valvoline is good oil... But i was thinking something like Mobil 1. But if i can find royal purple should i go that route?

[PaganEgyptian]

1000 miles after a rebuild or a new motor? Your definately ready for a change, hopefully some of this info may help...


The new Pennzoil (post Y2K)is a Hydrocracked motor oil, Hydrocracking is the best and most expensive way to purify oil. There are currently only 3 companies that do it. Conoco, Motorcraft(made by Conoco), 76 and Pennzoil. I have tried Mobil 7500 5W20 and after 2500 miles, I am not so happy with it as it doesnt feel nearly as slippery as the other oils I have used with the same mileage use. Havoline, Valvoline, and the 80% of non-recycled Castrol is HydroFinished the other has been known to be recycled oil but not confirmed, which is a cheaper way to clean impurites out. Be aware of using anything that says it's Parraffinic, thats what causes sludge if used for extended amounts of time. Kendall used to be Parrafinic, but I think they quit making that blend due to the number of cars that had to have rebuilds due to sludge. Most House brands are Parrafinic blended as its the cheapest way to make it. I dont think that the blend is able to meet SL requirements -Tim
* Quaker State oil is not Hydrocracked like Pennziol even though it is corporately owned by Pennzoil.

[Phoenix57]

is this including real synthetics?

[Firehawk 526]

Mobil One Syntech 5w-30 since first oil change

[PaganEgyptian]

is this including real synthetics?
Yep, the base oil is the same, the differences in Synthetic is the additive package. Not the base oil.
