What type & weight of oil do you use?
This may sound like a newb question to most of yall but I'm posting it to get others incites, So like the title says... What type of oil (normal, blend, full) and what weight oil are yall using in your cars
Right now i am using 10W30 synthetic blend in the original SB 327 that came in the '68. I have heard that in older motors switching to synthetic blends lead to leaks but I dont move the car much as it is a project but i haven't noticed any leak or negative.
Thanks for the input guys

~2003 Impala - T61 Turbo, intercooler, Plog, much much more

I use 10W30 or 10W40, with a preference for 10W40.
I use whatever brand I can get the cheapest. I wouldn't buy a brand I've never heard of but any of the brands they sell at any of the car places are fine with me, even the house brand. I'm probably a little sucked in in that I would get Valvoline or Castrol preferably as long as it's cheap.
There's few things that have the bullshit involved that auto oil does. I think almost all of it is hype. Here's my 2 cents:
No one ever had cavities because they used the wrong brand of tooth paste. It's not the brand or the type of toothpaste, it's simply doing it or not.
I don't think it makes a big difference what oil you use as long as you change it routinely.
3K mi = early but good
5K mi = ok, right in the middle
7K mi = you're pushing it
I'm not big on the synthetic oils, I'd rather put the money towards other things.

All oil on the market that is API-SM rated is fine, even the house brand oil, to use in car engines. Even the non-synthetic oil.
Same with oil filters as well. No car manufacture voids the engine warranty just because all the oil change receipts show that only house brand oil or the cheapest filters was used during the course of the engines life. If the cheapest filters were as bad as some have claimed then the auto manufacture would pass out their own oil filters: 1) as a protection against warranty work, 2) as then would be required by federal law for requiring only their filter to be used.
I change mine between 4 and 5k miles, use the house brand dyno-oil and house brand or Fram filters most of the time.
