We have used Mobil 1 in our Toyotas for many years now, and I've seen people on here talk about using Rotella. I would only take the car on drives that last at least 30 minutes (no milk runs -- those are reserved for the gassers). Also, what oil type should I go with/what else should I look for in the oil? How often should I change it?

Sorry if I'm starting a fight here...

I'd do one of the modern 5W40 oils if the car isn't a leaker. If it is a leaker, I'd do a dino 15W40. I don't really know how many other choices there are today.

FWIW, people are reporting that W*mart is now selling Chervon's most excellent DELO 5W40 oil for around $19/gallon. (You'll find multiple dino and syn diesel rated oils at W*mart.)

Drain intervals are going to be a function of what kind of shape your injectors are in and how much soot you are producing. The only way of nailing this down is to do some sampling and establish a baseline for the engine. I'd be sampling at 5,000 miles and determine if you can go beyond that. Diesels can generally go for longer intervals with ULSD as the soot production is so much lower now.

This. 5K on any of the name brand 5w40's is safe. No need to fear a few short runs, either - take it out on the town for an errand or ice cream periodically. It won't bother the engine as long as that's not all it's used for.

Do gasoline engines suffer from fuel dilution more or do non gear heads akathe general public idle a lot?
I ask this because more often than not when I changed motor oil it reeks of gasoline, however my E320's dipstick does not have this smell.


I don't idle over 1 min unless at drive through.

Thems fighting words

I have always only used 30 w oil in 'all' cars I have ever owned. 'Here' is socal coastal, and it snowed here the year I was born & once again in 1967. Never had a hard frost (frost is rare anyway) (rarer than rain!) I've never had the need for multi-vis oils. Originally Valvoline (old label =API CC) then to Pennzoil (old CD). Never any problems

53 chev actually used reclaimed oil 11 cents a quart!
67 VW (about 5 bugs & buses)
75 ford pu
79 VW Rabbit diesel (x2)
82 chev 6.2 d (x2)
84 MB 300 TD
84 chev blazer 6.2
83 MB 300cd
& a few others

Well Jooseppi doesn't live in socal, but he lives in Maine. Plenty cold in the winter. I have been so happy with Mobil 1 (5/40) since I started using it 5 or 6 years ago. I think it is labeled for Diesel Light truck or SUV. I probably put on 7,000 per year, run it 50 miles a day for 150 days a year and change it once a year. I drive it hard when the engine warms up. It uses no oil, leaks no oil and so I add no oil, by the time I change it in October, it is pretty much down to the add oil mark. I check the oil level at least once a month.

On a hot day what is your oil pressure at idle? The older diesels may preffer straight 40 grade diesel rated if you can aquire it for the same price. Thirty weight in older diesels is different than thirty weight in modern diesels.

I can see no harm in using the 40 weight. If the weather did not swing so bad temperature wise where I live Single grade oils would be in some of my cars.

i use 15w40 weight oil,for the best diesel oil use Cummins brand

Ditto here; Valvoline Premium Blue is what I use. When it first came out in the late 80's it was known as Cummins Premium Blue.....good stuff for dino oil.

X2 on the Valv Prem Blue. The napa fleet 15-40 is speculated to be the same, but cheaper, and goes on sale more. Always seems like the oil loss over time is less when I use that oil. Tractor Supply has a 15-40 fleet oil that is also well made for the price.


Get a metric o-ring set (autozone?) that has the little o-rings that go in the filter housing and change em out too - there is a forum thread on that.


My personal method is to unplug the glow plug relay so I can crank the engine over for several seconds to build some oil pressure before the first start after an oil change.

Rotella T6. 5W-40. Perfect for all climates.

Change it every 6K miles.

The filter easily goes 6K miles and this oil is more cost effective than the Dino crew who change it every 3K and, as a benefit, it provides a much easier start in the cold.

Actually, I live in Massachusetts. Wish I lived in Maine...

Hmmm, I remember Roy saying he goes up 9000 miles between oil changes. I may try averaging you two out... do you recommend using Mobil 1 10W-40 in the car at all? Please don't ask why...
