Castrol GTX Diesel 15W-40

[want-a-be]

Has anyone had any luck using Diesel Castrol in their motor home?

I have been using shell rotella in my pickup for 13 years. I will use it in my new to me DP also.

I don't think Castrol was even in the Diesel oil market until maybe 5 years ago, at least I never saw it on there web site. Please correct me if I'm wrong

I use Shell Rotella T6 full synthetic in the Ford F-250 6.4 liter diesel. The VW Jetta Sportwagen TDI gets Castrol at the VW dealership. It's one of the very few oils you can use in a VW diesel. Both the Shell and the Castrol are good products and you should have good results with either.

Castrol is now BP's oil brand. BP blends the same range of lube products, using the same additives in pretty much the same proportions as all the other major downstream operators: ExxonMobil, Shell, ChevronTexaco, Phillips66. Industry standards require the brands to be compatible and interchangable for equivalent products.

One or the other of these blends the products for manufacturer brands like Honda, Motorcraft, Toyota, etc. I know the Ponca City lube plant was blending for Honda and Ford ten years ago, but those contracts may have gone elsewhere.

The only reason I have for avoiding BP products when I can is that I worked 22 years in the industry, more than twelve of those on industry-wide joint projects, and hated the way BP tried to do business whenever I worked with them. So I would rather not give them my money to help keep them solvent.

Is there some reason why we shouldnt be using it? I know its a lower-grade oil, but apparently it was better than most of the 'bought in bulk' oils.

You are dead wrong on Castrol being a low quality oil. We have used it for years and it was a highly recommended oil By VW and Porsche back in the day. It could handle the high heat of air cooled engines with out break down. :R

Yeah,
I too wondered where the idea of Castrol being a "low quality" oil came from too. I'm by far, no oil expert but, as far as I know, Castrol's been used widely in a zillion cars, trucks, motorcycles and more for decades and, with a good following too. I use Delo 400 15-40 as a choice for our C-7 CAT.

I use Motorcraft 15-40 Diesel in a Cat C7, change once a year.

If it meets the mil-specs of your engine, you can certainly use it.

BUT, one of my criteria for choosing oils is that I can find it as Walmart, auto parts houses, truck stops, etc anywhere I go.

So, that means Shell Rotella T and Delo 400

[Rollnhome]

It seems on the East Coast Shell is very popular. On the West Coast Chevron Dello is the preferred. I have been around Cat and other heavy equipment for most my life and Dello was the oil to use.
In the motorhome I use Delvac. That is because that is what Freightliner shop uses. In my personal cars I used Castrol for years, it seamed to keep the engine internal parts cleaner.
As long as you use an oil that meets your vehicle specs you will be fine.

I have never seen an engine fail when using the speced oil. I have heard of kickbacks to auto manufactures for promoting a certain oil or other products.

Now for my personal cars I use whatever brandname that is on sell.

[Garry_Gayle]

Just use the tried and proven Chevron Delo 400, my brothers Peterbilt has over 3 million miles running it. You can get it anywhere Costco, Walmart, and every truck stop in the USA.

Have used Castrol for years with excellent results. As long as a oil meets or exceeds the API rating for the engine it should work fine. Oils with higher detergents will help keep the engines internals cleaner longer. Full synthetics will be of benefit in cold start situations.

[John_Joey]

As I was taught, diesel engines are dirty engines and require a higher amount of detergent in the oil. The only real problem I ever heard of was when a really dirty gas engine was fed diesel oil it broke free the dirt and started to clog oil passages.

That was back in the day, and may no-longer hold true for todays engines/oil.

Most Castrol oils are HIGH quality. They meet the tougher European standards. The question about "luck" with oils makes no sense. NO RV'r drives enough miles to determine that an oil is good or bad. You would need many millions of miles to come to a conclusion. When was the last time you heard of an RV'r that had engine problems due to an inferior oil?

I think shell is used primarily because its been tried, tested, and true. You are trusting a machine worth more than most people make in 4 entire years to the maintenance you put into it.

For the $5 its going to save you, is it worth the stress?

We use it because our trucks are replaced regularly, maintained vigorously, and when speaking in terms of oil consumption of a fleet over the course of a year, these factors justify it for cost savings.

If it was my coach, I would be running synthetic mobil-1.
