Synthetic?

[shroomjohn]

Just wondering if anyone knew if it was going to be coming w mobile 1 like the vette or someting else? Also is the ss going to rec. 91 on gas or are the sayin 87 will be alright thanks

[CamaroSpike23]

more than likely it will come with mobil 1 and be recommended for 91, but ill be changing the oil after teh first 1000 miles anyway to Royal Purple, and i dont put anything less than 93 in my cars.

If it doesn't I will switch it. I always did a dino change at 500 and then a synthetic change at 1000 anyways.

I will only put in Amsoil and donaldson filters

[shroomjohn]

So is it a good idea to change at 500 or 1000 miles or is that just personal preference.

Ill be changin it at 500, 1500, and 3000. then after that every 3000. It's just personal preference for me. You can never change the oil too much. But unlike the others i will be staying with the mobil one synthetic. I run it in my 71 chevelle, my 04 silverado, and i ran it in my 02 camaro ss before it was stolen and ive never had any problems.

The reason new cars needed changed early was the "break-in" period. engine assembly/machining tolerences have gotten a little better in the last 30-40 years. I will most likely change at 500 miles then go longer on the intervals. If I changed every 3-5,000 I would have an oil change due every month. I go about 10,000 on the VW with synthetic. I would go longer but it only has about 4.5 qts in it.

I plan on running Royal Purple in it after the break in period and it will probably knock on anything less then 91

Nine quarts for the LS3, going to get expensive if you use the good stuff.

i doubt it will knock running lower than 91, but it will retard the spark timing to prevent the knock.

yeah, but why cheap out on one of the most vital necessities in the motor?

[Muscle Master]

Heres how I like to do it, its different with Hemis

3000 miles on synthetic or every 3 months, which ever comes first

I used Q horsepower and had great results I like it but now I'm running Royal Purple and mobile 1 filters and don't think I'll go back to Q

You are correct AMSOIL is #1 in synthetic oils many test have proven this , after all they were the first to produce synthetic oils years ago and have the most experience with it , using synthetic oil will improve your MPG plus give you a little more HP and of course increase the longevity of your powertrain it is a no brainer .

Had no idea it used that much but it will be worth it

I heard lower then 91 puts a knock in corvettes

Have a look at this site:

http://mototuneusa.com/break_in_secrets.htm

There's a lot of good information and this chap emphasizes NOT using synthetic during break-in. Whether-or-not you agree with everything, I think it has a lot to think about.

ALSO, check out "Patman" on LS1tech. Try searching "oil analysis." I can't find the post I was originally thinking of, but I thought he had made a spreadsheet, of sorts, that had a lot of comparisons between several brands with the results of lab testing on his engine oil. It was very interesting.

Ooo... I found this too: http://www.bobistheoilguy.com/

you clearly know nothing about dodges... if you do infact av an srt8... and its new... like you say... dodge will change the oil for you every 5000 km... for free with full syn recommended... i have a charger and a viper and soon a challenger srt8

[Shifty 6]

OK I'll bite....What do other engine builders have to say about break-in?

Check out the links I posted above

Synthetic oil should be used in not just the engine but the tranny and rear end to get the MAXIMUM benefits ...

Dang, thats a lot. IDK where the vette LS3 and Camaro LS3 differences page is but will they have the same oil pan for all that oil? If you think about it the Camaro could hold more oil since the engine will be higher off the ground, hence bigger oil pan.

what would you suggest using? i havent really found one that stands out above the rest? ive heard good things about Royal Purple and Q horsepower, but i havent had a chance to use them... any suggestions?

Well, i dont know if this will help but.A friend of mine Has a chopper and likes to cruise long distance on the Weekends.His wife rides on the back and Her legs are close to the motor and she complains of the heat.She says its almost to the burning point.After he changed to Amsoil in his chopper,the motor temp has gone down considerably,and its more of a pleasure to ride now for her.


They have also ran amsoil in big rig trucks for 80,000 miles while only changing the filter.The motor had no sludge in it,There was no viscosity breakdown,and oil analysis shows that there is less wear metals in the oil (after 80,000 miles).

To me its worth the money

I'm using Amsoil, Expensive but the company claims it's good for one year or 20,000 miles before changing is needed. Also hear great things about it.

I would not worry about synth during a break in. I have one of the first ones broken in with it (early 1st year LT1 in my vette, mobile 1) and it's doing fine. But do change it early to get out contamination.

I have used AMSOIL for years it is a great product not as well known as ,Mobil ,Q etc.. because they don't advertise as much which I think they should ,but way better in every test I have seen. It is pricey but you get what you pay for .
REMEMBER AMSOIL WAS THE FIRST TO SELL SYNTHETIC OILS IN NORTH AMERICA SO THEY KNOW HOW TO MAKE IT THATS FOR SHURE I personally wouldn't use ANY other brand...

[radz28]

Did Germany first develope sythetic lubricants in WWII? I thought I read/saw that somewhere.
