Ok kind of a dumb question, but what kind of oil are all of you guys using?
Like penzoil
mobil 1
castrol
valvoline
whats the best in your opinion
I was brainwashed as a young lad to use reg.penzoil but i know there has got to be better on the market now.

 

i use castrol 10w-30

I used to use havoline 10-30, but I've changed to mobil 1 15-50.

what differance does it make waht oil i use? if you're going to run a oil based on a popularity contest i'd be looking else where for my info, like national sales figures, or even what oil sponsers the racing i like. i believe it's better to have oil and filter that are changed on a regular basis than a big name or high dollar oil that isn't.
i use pennzoil and mobil 1 for all my cars. trucks, and equipment.

i use mobil 1 and nothing else period because of performance it has given me in the past. pennzoil is one of the worst oils when it comes to sludge build up, but changing regularly combats that. mobil 1 will not sludge up period. no matter how long your intervals are between oil changes.

 

I've been using mobil 1 15W-50 for a while and am very happy with it.

 

I went from valvoline durablend, to valvoline tri-synthetic, to mobil 1 tri-synthetic, and have been very happy with all of them. I think it makes the car run better, of maybe I'm just thinking it.

Ede got it right. Use a good brand and change it and a good quality filter every 3000 miles. I use wal-mart super-tech synthetic(quaker state) blend and baldwin filters for a very long time without any problems. A good filter makes a huge difference. The farmers around here can show you the difference in cheap filters when they run a deep well 24x7 for weeks at a time. Poor filters(fram for example) plug quickly allowing bad oil to return to the pan, sometimes the filter even breaks down and the filter element ends up in the pan.

Over 175,000 miles with Mobil 1 5/30. Hardly burns any oil, no cloud of blue when I start up. You can pay a little more now, or pay a lot more later.

No regular brand of oil has ever stood up as well in my 30 years of driving.
