Just changed oil to Valvoline Premium Blue 5w-40 synthetic extreme. Just wanted to know if anybody has tried it and how long you keep it in before a change??

 

What filter are you using? I haven't tried this particular oil, but the Cummins is so easy on oil, I'd run it to at least 7,500 miles if using a quality filter like a Fleetguard Stratapore.

 

I have been using the Fleeguard.

 

Ozzie where are you getting it? And what's the going rate? I only checked one place around here and they wanted $30 gallon for it.

 

Thats awful steep for a group III synthetic...

Youd be much better off with Mobile Delvac 1 5W30...its a group IV and FULLY synthetic....

 

The Rotella "synthetic" 5W-40 was $12.88 a gallon last time I got Delvac at Wally-Mart. For the price, it's a great oil. It doesn't get cold enough around here for me to spend double what I need to on oil, though.

 

I always just use the same oil throughout the year, 0w-30 Amsoil series 3000, never had any problems. Also I run it for a year and always change it in the spring. The filters get re-placed every 2000 miles, very simple just spin off and spin on, takes about 4-5 minuets. Good luck.

 

it's 12° outside today going down to 8° or so later tonight and I just run Chevron Delo 400 year round...

Sorry it took so long to get back. 6cynlinders--I paid 85.00 for the complete oil change at valvoline rapid oil. Thats 12 quarts, filter and labor.

 

It's your truck, your engine. I WOULD NOT RECOMMEND anyone use THIS oil in their CTD! I cannot find anything that states this oil is diesel rated. You need the extra additives in HD diesel rated oils for soot and acid control. This oil may be fine in a gas engine, not a diesel. If opting to spend extra for synthetics, there are plenty of full 40 grade HD oils on the market, which is what I'd look for, especially if towing.

 

Just switched mine to Cat full synthetic DEO, the MSDS says it is made by Mobil-Exxon, and as far as I can tell, and from what our oil supplier says, it is just rebadged Delvac 1. Plus I can get it for around 20 bucks a gallon at employee cost.

I have already noticed a slight MPG improvment, but I am not sure if it is the oil, or a change in my driving habbits. When I finish this tank of fuel, I will get a better idea.

 

What's the matter, don't you know that Amsoil is always superior to any other oil, regardless of application?

I changed to Petro Canada Duron 10w30 when I was visiting Saskatchewan, Can. at Christmas. It was -30 celcius. I needed a change anyway. 15w40 Delo was too thick even at -10.
I change at 125 hrs in winter and 150-175 hrs in the summer.
Diesel oil is built for higher shear strength. I wouldn't put 0w30 in my truck. Although we did use it in the old JD tractor on the winter-it was the only way it would start. I tried 0w30 in the Nissan 240sx, and I thought it was too thin for that.
