any oil recomendations??

[transmaro93]

hey guys first off what is a good time to change the oil for the first time on a fresh build (still has crappy oil in it for initial start up) i put probably like 10 miles on it, but it has been run alot in my driveway since first start up. Im going to run synthetic, does anybody have any oils that they swear by. Builder told me mobile one, but im just seeing what everyone else is using. thanks

Pennz or RP.

Amsoil.

Hot Rod magazine did a test that showed Royal Purple DID add 2-4 h.p. when compared to all other oils. I use 5W-30 and it also can be used for up to 7,000 miles. I know you'll never feel 2-4 h.p., but every little bit adds up.

ya dude royal purple is the good stuff, hit that up at 5,000 miles a piece and you'll have a good long running motor

I assume you're running a roller cam? If so, most of the synthetics out there will work fine for you. Amsoil has a good reputation along with Royal Purple although I can't comment on them personally. Seem like overkill for my use (too much $$ per quart). I use Pennzoil Platinum full synthetic in my truck and it works adequately. I've also used Valvoline's full synthetic with adequate results. I think just about any of the full synthetics out there will work fine for you.

I don't understand how some people can tell the difference between some of these without having a professional oil analysis done, other than fuel mileage and the fact that the engine still runs with good oil pressure. Most of it is just heresay I think. Just be sure to stay away from synthetic blends, if you want a true "synthetic" oil.

High end synthetics are actually cheaper if you run the recommended extended oil change intervals. Amsoil has an oil with a maximum change interval of 35,000 miles (although I wouldn't go that far due to consumption and such). I do use it in my delivery van and change my oil every 20,000 miles. It is now up to 353,000 miles, ~175,000 of which was on Amsoil.

only thing is amsoil is hard to come by... where do you get it? thanks for the info guys and yes its a HR cam...

Advance often runs deals on castrol synth & better filters (k&n, pure1) for like $24.99

[JSPERFORMANCE]

Amsoil is great stuff. We run it in everything.. The XL series motor oil costs $7.25 a quart. Available here at JSP. We also do a package with 5qts of xl and a Wix filter for $45 + tax.

I have heard that myself, I was going to go through the process to become an amsoil distributor since work was slow, but decided not to do it in the end. I haven't used their products myself, but I suppose the oil change interval is just a mental thing for me. It would make me nervous to run 35000 miles without changing the oil or filter even though it has been proven to be ok. I'm a 3000 mile guy

I get it straight from amsoil as I'm a dealer, but I only did it for personal use and for my friends.

[edpontiac91]

I paid only $4.75 per quart for the Royal Purple. They had it on sale at Strauss Auto Stores. You have to watch the Sunday newspapers and check the flyer inserts. You can usually find one of the full synth oils on sale.

amsoil for me, i change it every 5.5 just cause i am rough on my car and i dont like the idea of keeping a filter in that long

[JSPERFORMANCE]

When we were trying new oils (after Mobil one changed their formula) I researched Royal Purple and used it myself. I found that it broke down alot faster than the Amsoil and even some conventionals. It always came out very thin where the Amsoil seems to keep its viscosity alot better. In fact we recently changed the IROC over to the Amsoil Dominator race oil and the car picked up .2 and 2 mph. I was sceptical at first but there were no other changes made and the DA and temp were the same as some passes last year where the car was the .2 slower.. I dont know for sure if the oil did it but I am not gonna run anything else..

[Syzygy]

.2 sounds a bit much, but awesome.

[jts98z28]

i run amsoil (my neighbor is a dealer) or RP

[JSPERFORMANCE]

Sy- I agree, like I said I thought no way but the car is EXACTLY the same as it was last season.. All I did to prep for this year was change the oil and plugs as usual. The timing, bottle pressure and fuel are all exactly the same.. No real evidence to say anything definate but with it being the only thing different from last season I am a believer.

I agree. Royal Purple is more hype and PR than substance.

I wouldn't pay the $$$ for Royal Purple. My own oil analysis came back with less than stellar results after only 3 20 minute track sessions and 3 or 4 autox events. The oil had already sheared out and had broken down. This similar what the previous owner of the car (2MCHPWR) experienced when owned the car. At the time he made the switch to Redline. So same car, two different tests, two different labs and the the same below average results from a supposedly top shelf synthetic oil.

I couldn't find Redline easily, so I decided to give Royal Purple another try. Not what I would expect from a full synthetic oil that makes the claims that RP does. Might be fine for a daily driver, but not for any kind of hard use (not abuse), just hard driving.

The car now gets Amsoil, we'll see how that holds up after it goes out for analysis.

I use Mobil-1 5w30 and I change every 3000 miles. I have a new build as well and I hanged it after the first 500 then after the first 1000. Probably overkill but it seemed to be good for my motor. I have strong pressure and when I change the oil the viscosity seems to hold up pretty well. Im not a mechanic or well experienced like some of these guys but personally its what has worked for me.

Amsoil for the race car, Pensoil Plat for the daily

[MonmouthCtyAntz]

Kinda figured this post was going to turn into an Amsoil ad lol...I used Pennzoil Ultra my last change...suppose to be better to Pennzoil Plat. 28 Bucks for 5 qts @ wally world.

[JSPERFORMANCE]

The problem with oils and other products in fact is when they become available to the mass market (wall mart, auto zone, etc.) the retailers are constantly pressuring the manufacturers to sell at cheaper prices. When a company is buying millions of dollars worth of product it tends to have a little pull to say the least. The manufacturers respond to the lower cost demands by finding cheaper ways to make their product.. This starts a snowball effect like we saw with Mobil 1 which is now more of a semi synthetic oil thanks to the cheaper base they are using.. I can't see Amsoil, Redline, Gibbs, Brad Penn going to the mass market in the near future, they all seem to be more interested in the specialty market than anything else.

i would run what the builders said, they built the motor.
