Motor oil is motor oil?

unless its cold out, i agree, 5w-30 is too thin

Just thought that I would add my $.02 to this train wreck.

I've used Castrol GTX religiously. I've only had one engine problem concerning oil ever, and that was on my 80' lude with 210k miles on it. The oil pump failed and I think I destroyed the engine, but it was -50degrees F and I don't know when the oil pump was changed before that and the engine had been beat on. with that said, Castol has always treated me well. I try to change my oil between 3k-5k, but if I have ever used anything else, I've always changed at 2k. In the end,

I have to agree with the oil is oil for those of us who are daily drivers. As long as you change it frequently you should be good.

is the oil light supposed to be on when I just have the key turned to the on position? (not running but like radio plays and stuff)

yes

I use:
Valvoline VR-! Racing 20w-50
or
Mobil 1 Super Syn 20w-50

I'm running 5w-30 right now and i plann to switch back to 10w-30 soon. I realized the manual is telling me an average temp reccomendation. Since I live in california where winter is not a season, I might as well get 10w-30 since i dont get really hot summers either.

I don't use synthetic and my oil gets change every 7000 miles. What is the purpose of changing your oil so frequently?

[speedpenguin]

i use 10w-40 in summer and 5w-30 in winter.
it works out for me
cuz MD is definitely hot in summer and cold in winter.

maybe I'll try the 20w-50 my nexy oil change.... just to see how it goes.

[XxDark_AccordxX]

my manual said to use 10w-30 and thats what ive always used. i use 10w-30 high milleage.what does 5w-30 do? does it make it run better or something?

[89cordlx]

the oil is less viscus and flows easier in low temps.

maybe I'll try the 20w-50 my nexy oil change.... just to see how it goes.

it's not THAT hot in ohio, is it?
10w-40 would be better, i think.
oil that heavy would be for if you live in like south america or africa.

[89cordlx]

I'll have to talk to one of my mechanic friends about it...

[NeubJ]

I was being lazy and decided to go get my oil and filter changed. I was gonna try 10w40 and the guy there said it keeps the heat trapped (basically saying it was bad).
Then he tried to tell me to go with Mobil 1 High mileage (plus the sales pitch). I just wanted to stick with the brand I normally use and he kinda got pissed since I didnt say ok.
Everyone says something different about oil.

[superguillermo]

Yes....a TRAIN wreck!!!
