Funny you mention the filter... search for oil filter on youtube and see what comes up. I used to buy Fram filters all the time, but never again! You'll have to see for yourself, I can't put it into words. I'll probably stick with Bosch, but I'm considering Mobil 1; it's twice the price of Bosch but I think it may be worth it. Feel free to opine!

I use Pennzoil Platinum 5-30 in all three of my cars: a 2007 Vette, 2010 Equinox and 2005 SSR. I change when the computer tells me to, or 8,000 miles, whichever comes first. I use K&N filters on all of them.

I've used full syn after the first few oil changes, and have used 5w20 until recently and started using 5w30 and change it between 5K-10K depending on how I drive. And try to use a decent filter with the anti drip back valve...

Rotella T 15-40 in Duramax. If I didn't buy a 55 gal drum I'd probably be using Amsoil synthetic. They've been doing it longer than mobil 1 I think. I use just Amsoil in my tranny for right now.

I do my own oil changes and have ever since I owned a vehicle. I usually use fully synthetic 5W30 and I usually buy the generic brand. I used to change it about every 5,000. However the last few years I've just been changing it a few times a year (before summer and winter set in). The reason being is that we don't drive the vehicle much (living only 4 blocks from work certainly helps) and it just makes me feel better to know I have clean oil in the vehicle. Depending on how much driving we've been doing I may only change the filter once a year.

I was reading a while back that the Wally World SuperTech syn oil is actually re-badged Pennzoil synthetic, fwiw. They stamp the same batch codes on both, same contacts on msds, etc. Their filters are more efficient and are of better media than Fram as well. Surprising considering that they're less costly. I don't know anyone that loves Pennzoil, lol, but you can get the same oil for 2/3 the price. :stretchgr

Always Mobile 1 full syn every 5k miles. Also change the trans fluid every other oil change. Current truck has 170,000 miles on it and should be here for another 170,000.

wow, tranny fluid every other oil change? Is this something that should be done regularly, or are you just extra cautious?
Extra cautious because I tow a ton of crap with this truck. Haul a boat around about 150 days a year, 4 wheeler and trailer another 30, etc, etc...better safe than sorry.

well I went ahead and got some Castrol Edge 10W-30 and put it in my truck. Also got a Bosch oil filter, never using a Fram again! Still debating whether I'll use it for 15k miles, but will surely go at least 10K changing the filter every 5k. Thanks for all input on here, gents!

Mobil One in the Jag and Mercedes 560 every 10K. The Mercedes is an 86 560 SL and the mechanic said it will reduce oil leaks int he older engine sealing gaskets better. Seems to work.

You don't need to swap weights of oil for cooler/warmer weather. Go with what the manufacture recommends as far as weight. I buy BMW oil for my 525 which is recommended to change every 15K...I change every 8-10k..In the Explorer I use 5w20 motorcraft (factory recommended..I have 106k on it now)...I had a 97 F150 that used 5w30 but had some small leaking seals. I started using Valvoline 5w30 maxlife and it swelled the seals so it did not leak anymore..I would recommend that for cars over 150K in mileage.

You're supposed to change the oil? I just throw some kitty litter on the puddles and add a quart each month.
