i couldnt really tell if there was a def b/c the day i got the car i change the oil to the one stated above... been running the car on this oil for about 6 months now... and change oil and filter every 3000 miles...
my car doesnt leak oil

should i change my brand of oil? and the wiegh/rating to?

y do u think ur running wrong oil?
i run 10W30 Amsoil full synthetic on an engine with 200K and it's fine..... it actually seemed to have started running smoother after switching to the synthetic....

The main reason people don't like synthetic is because on an old engine it can cause leaks. But if you have no leaks then more power to you. Keep using synthetic if it's working as good as u described.

or if you can afford changing it every 3000 miles. full sythentic is suppose to be changed around every 5,000 miles...or what it 10,000?

Amsoil is great stuff! I second that, no problems after switching . . .

I run the SAE 50 valvoline race oil they have.... mainly because I fear blowby from my tired engine, and the thicker oil really seemed to help reduce it.

Yup I use the 60wt valvoline race oil, holds oil pressure fine and no problems yet, been running it for about 4 months now... aight peace :chicken:

i like 10w40 and 15w40 my self, except you dont see 15w40 around too much, i think diesel trucks use it more than cars do.

the afformentioned weights always gave me nice oil pressure at idle, thats with the stock gte oil cooler set up.

 

[stratoayu]

you guys arnt having problems running a 60wt in the winter?

 

[Spoolme]

ive never even seen a 60wt!! :O

 

[Chrisco]

5w30 in the winters of chicago... 15w50 in the summers... always mobil one synthetic

 

[tetsuye00]

20w50 Mobile1 synthetic in hot as hell Florida. Last time I pulled the head it was clean as a whistle.

Where do you get 20w50 Mobil1? I can only find info on 15w50. Even their site doesn't have Mobil1 listed that high.

Nope, I live in CALIFORNIA aight peace :chicken:

 

[Justin727]

i just run 10 w40 castrol regular shit but i put about 7k miles on the car this year, although it runs real smooth and when i popped the valve covers off it was real clean, no varnish!!!

 

[sportinct26]

what the... i havent even seen those 60wt, 90wt , etc..


anywho back to hp's question.

if your car is running FINE in the oil that your using now WHY CHANGE IT? WHEN you change oils(rate) your risking your engine IMO. WHY change something that works already right?

im running same thing as you and when i took out the valve covers to replace the egr cooler my crankshaft is SQUICKY CLEAN AND I MEAN SQUICKY CLEAN...when or if i rebuilt my engine the internals will prolly be in the same condition...

i change my oil around 2500k to 3000k...

i dont like it when my oil starts to turn black...

Amsoil Severe Racing formula 20w-50. My 1j loves it.

bla bla bla blaaaa, another oil thread. SYNTHETIC IS FINE IF YOU DONT HAVE ANY OIL LEAKS! IT DOES NOT MATTER IF YOU HAVE 4562762472 MILES!!! Redline 10w30 and 10w40 in all my cars, and a bottle of oil treatment. My supra has about 230 k and the MR2 has 184k. It's what is keeping them alive.
