I'm at the point where my cats are already toast and my engine is way past the point of any sort of warranty.
I hear you, some of us still have to maintain install emissions parts I have a new short block myself. plus a lot of us rely or have other forms of transpotation that are newer just good stuff to know. Im located in arizona phoenix. I got a deferral an also showed discontinued parts with manger statement. if a car is imported over 21 years its federal emission exempt. but here they make you go from dmv to dmv inspection til some dork says no an yes then they takes pictures of devices! a camera. i had know pair reed valvue block off plates an sandwhiched on egr they didnt notice, took me a month to source all parts. you also cant install a heavy duty rated diesel in regular truck unless rated heavy duty. ridicuols but many states such as montana dont emiision test. when i lived back east we would register are cars in va they had a seperate window sticker for emmisins an cops wouldnt know to an cant inforce a other states law. so we would go years wit out emissions inspection. in az they ride around looking for poeple an citeing them a warning entering them in sytem for out of state tags like a counter even if a return vister you have go court an show statments of out of state adrees. im leave it at that.
 
FWIW... I have used M1 10W30 High Mileage for a couple of years now and just recently switched M1 TDT 5W40. I have had high oil consumption + oil leaks (adding about 1 qt every 400 miles or so) when using the M1 10W30 High Mileage. Since switching to M1 TDT 5W40 about 1000 miles ago, I have not added any oil (low engine oil light has not lit up, and yes, I am also checking the oil level). I have lost some oil since switching (due to consumption and leaks), but it is significantly less than when I was using M1 10W30 High Mileage.
This response makes me want to switch. I've been using Mobil 1 10w30 or 10w40 Full Synthetic for years and I've always had a consumption issue. I was looking at Rotella but I want to stick with Mobil 1. I didn't know they made a Full Synthetic Turbo Diesel Truck formula until your post.
 
Well, for full disclosure, the friendly low engine oil light has now started to toggle on/off when driving. I did the math since my last oil change and I am at 839 miles... so, not at 1000 miles like I originally thought, but I am at least going twice the distance I previously was when using the M1 10w30 HM.

I am sure the Shell Rotella is great stuff, but, like you, I've been a Mobil 1 guy for a long time and it would take a lot for me to switch.
 
I recently changed to M1 5w-30 full synthetic extended performance, I have 2k on the oil and my oil light comes on at start-up while its warming up, the nice thing is that this oil has quieted the engine noise on start up as well. I did however notice a little seepage from the valve cover gasket on the front of the motor and the gasket is new. Now im trying to figure out, what oil i should switch to next as this engine has been on dino oil until i made the switch...

im somewhat new to the forum and used the FAQ's however the last update appeared to be years ago which the industry has changed and we obviously have move miles on our vehicles since then, im also at 240k mi.
 
hmmphhhh ok i can give it a shot, which filter do you run with that oil?

edit - just ordered the factory filter from my local toyota.

Baldwin B2 filter.
 
Rotella T5 15-40, Purolator Boss filter PBL30001. No start up rattle

edit: oil filter

You use same weight as well 15w-40?

Yes, I am in a warm climate (very warm).

In the summertime I also add/substitute one quart of Lucas Oil Stabilizer every oil change.

I use a Motorcraft FL1A filter.
 
Do you have engine noise at startup since it's a higher viscosity? and from what I have read, just disregard that it's labelled for diesel engines?
I have been putting delo 400 in my cars for some years now and these days most “diesel” engine lube oil is SN rated for gas engines too.

Last oil change my 80 got O’Rielly 15-40 that was dirt Cheap on sale.
 
What about Mobil delvac 15w40? Any body has something to say about that one? Only ask because I run tht in my semi and it’s super cheap at Sam’s club. It’s great in my Cummins engine run it 15k no problems and I would like to try it in my 80s.

I’ve been using it the last two changes. No issues, no usage. I had hoped to have a Blackstone report to compare to the Castrol GTX 10w30 I’ve always used but USPS lost my sample.
