Engine Oil Reference Thread

[nthach]

I dunno, since the two Benzes i work are gas, but here goes:
1986 420SEL: Chevron Delo 15W40, with OE-spec filters, 2 times a year
1984 380SL: Castrol GTX 20W50, also OE-spec filters, 3 times a year

Both diesels:

RedLine 15W-40D(Diesel)
Change 8-10,000 miles depending upon city/highway miles

RedLine actually recommends changes at 10-12,000 miles but I just can't bring myself to wait that long.

71 280SE Castrol GTX 20W50
83 300D Delo 400 15W40
88 420SEL Castrol GTX 20W50
94 E420 Castrol GTX 20W50 (once I get it back from the shop)

Oil is changed every 3k or so

Other cars of mine usually got Castrol 20W50.

300SD 3K Miles on Mobil 1 0-40W
F250 2K Miles or 1 year on dino 20-50

Delvac 1 5W-40 - every 6months (about 1,500 miles)

190D 2.2 (201-601.921)
Delo 400 oil,
3.5 to 5k miles depending on conditions.

Wix filter's so far, plan to try Baldwin if app is available.
Filter every other oil change: unless really dusty, etc.

(At least the MB cost's less then half of what the oil change cost's on my KTM's.)

1999 E320
Mobil 1 SuperSyn 0w-40

1982 300D Turbo: 5W-40 Delvac 1 every 5K
1993 300D 2.5 Turbo: 5W-40 Delvac 1 every 5K

Currently:

MB - Pennzoil 15W-40, 3K miles
VW - Delvac 1300, 5-7K miles and growing
Toyota- Pennzoil HD30(summer) and 10W-30(winter), 3Kmiles

[Dana B.]

VW '00 TDI: Delvac 1 5w-40 10K
MB '91 300D 2.5T: Petro Canada Duron 5w-40 7.5K
- May ultimately switch to Mobil SUV & Truck syn, 5w-40, same as Delvac 1, for both cars.

[Hatterasguy]

300SDL- Delo 15w-40, every 2.5k-3k
Toyota Camry- Castrol GTX High Mileage 10w-30, every 3k

[MT_Merc]

Always used regular Castrol GTX on everything.
Fairlane: 10W-30, 3K
E150: 10W-40, 3-5K
Escort: 5W-30, 5K
Civic: 5W-20, 7.5K
F100: 10W-30, when I feel guilty about it (it's not driven that much)
On the Fords I always use Motorcraft filters, they're made by Purolator and are almost the same as the Purolator premium filter. I avoid anything that says Fram or Pennzoil.

First:

1984 300sd Delo 15w40 every 3k mi. w/ new filter
2002 VW Golf TDI Amsoil 5w30 every 5k mi. w/ new filter.

Now here we go:

I've noticed that the survey results show that quite a few of us are split between using 5w40 and 15w40 in our old diesels. What are the benefits and drawbacks between these weights?
Also, is it necessary to change the filter every time you change the oil? I do it just for cheap insurance.

1992 300D 2.5 Turbo: Delvac 1 every 7500 miles.
1996 Volvo 850 Wagon: Mobil 1 10w-30 every 5000 miles.
