What engine oil are you running?

[lahar50]

Rotella 15-40 year round.

For those of you in cold climates, you should not be using a 15-40 oil in temps below 30f. Switch to a 5w or 0w oil for winter.

Will switch when it gets to below 30f.

I use Castrol Syntec 10-40

http://www.castrol.com/castrol/productdetail.do?categoryId=82915479&contentId=6030819

and filter 90915-20004

every two or three years. There is a Castrol drive thru place near where I live, so its an easy way to go.

I use 0W30 German Castrol (GC). Explained here:

http://theoildrop.server101.com/forums/showflat.php?Cat=0&Number=711450&an=0&page=0#Post711450

GC is on the thick side of the 30 weight scale.

I was previously using M1 5W30 Extended Performance, however, it was burining half a qt or more every 1000 miles. I found out on the above forum that this specific M1 is on the thin side of the 30 weight scale.

I no longer burn a noticable amount of oil with GC.

I finally found the M1 0w40 locally (Toronto) and it seems fine... no start-up rattle (of course I didn't have it before either... knock on wood) - this went in in preparation for our winter weather which can be anywhere from "just around freezing" to real unpleasant..regardless there will be lots of salt even when the roads don't need it - I think the municipalities around here work on a "use it or lose it" budget.

Anyway the 0w40 does not have the SAE "donut" ....nor does the product shot on Mobils web site...wonder what ths really means... also they are selling M1 5w50 (synthetic) here as well now.- never saw it before last week - ...not listed on the Mobil site and was wondering what folks thought of it??

'97 LX 450, 207k Km

 

[Lka1988]

Summer months (hot)- Castrol GTX/Valvoline/Parts Plus 10W30 HM

Rest of the year (cold)- Kendall 5W30 HM, from work; inexpensive but good. Starts to smell really bad when it gets dirty so you know when to change it.

The SAE donut you are speaking about is the one that makes for a "fuel saving oil" and is usually only seen on 30 weights or 20 weight oils. Don't worry about it, it has nothing to do with the quality of an oil. Take a look in the FAQ or Bobistheoilguy.com for more information.

 

[97fortieth4me]

I use Chevron 10w-40 for both trucks. Since I deligently change oil every 3-4k anyway, so I don't see any reason to use a more expensive synthetic oil. And yes, I use genuine Toyota oil filters.

 

[Riad]

5-40 Rotella Synth, all year round

 

[Gumby]

10-40 dino. 3000 mile intervals. It's about a push for M1 at 10K intervals price wise. I like to go over the truck every few months any way.

When I did use M1 I got leaks. Went back to dino and they stopped.

0W-40 M1 in my Valkryie and will in my FJC

 

[GXO]

0-40 M1, year round.

ditto.

 

[MaddBaggins]

Chevron Delo 400 15w40

 

[Truckasaurus]

Ditto

Mobil 1, 0W-40 during the summer, 5W-30 during the winter. Change out every 7500-ish miles.

 

[jamisobe]

PO only uses 5-30 Mobile 1 Syn every 10K(mostly freeway), and new filter every 5k.

I will probably do similar or shortern the interval.

This what I've been doing ever since Ben Franklin told me it was a good way to operate.

 

[PACNW96]

I have used both 5w-30 and 10w-30 as IIRC are the primary weights in the manual for non-extreme driving conditions. In Seattle typically we don't see temps below 0 degrees F so I now use Mobil 1 10w-30 all year around.

oil

I have the LX 450 with 86xxx miles. Just put Valvoline 5-30 in (8 quarts). I have run Valvoline in all my wheelers and rigs (M715, Chevy Blazer, Samurais) Chevy truck and Ford truck with great success. I usually change it at 3000 miles. Live in MN.

Please define "great success."

 

[Cruiser Jimmy]

I've been told by a non-cruiserhead that one should run a single brand of oil and stick with it. Rotella, Castrol, etc. The additives that each company puts in are different and this is a large contributor to sludge build up.

I have always run Castrol GTX.

 

[whodat]

Rotella 5w-40 all year round every 5k, tried M1 and went through a quart every 500 miles.

 

[Nay]

M1 5W-30 in winter. Can see temps 20 below, but for a garage kept rig that isn't the biggest deal. Probably 5W-30 year round since I only see about 6K miles per year and will change at 5K-7.5K intervals.
