My goal is not to ignite a round of the Lubricant Religious Wars but is this for real? Even for my turbo diesel 300SD with 235,000 miles on it?

This is my 1st diesel and my 1st turbo, I bought it 10,000 miles ago so I am very noobie. I've been very happy with synthetic oils for my (non-turbo) gasoline cars over the years, changing between 5,000 and 10,000 miles.

My goal is to get this car well beyond the 500.000 KM badge, not to squeeze pennies on routine maintenance.

My one worry with the car: This car is not an oil leaker nor is it a blue-cloud monger - except when I step on it hard. Then, when the turbo charger engages, it looks like I'm skywriting on the highway. It THAT normal?

Anyway, the Amsoil guy recommends the following:

2 gals of Series 3000 5/30 Heavy Duty Diesel Oil $68
2 gals of ATF (automatic transmission fluid)--good for 50,000 to 100,000 miles--$62
2.3 pts Severe Gear 75-90 (differential lubricant) good for the life of the car.
Optional unless you want to do it now: Coolant. Vehicle capacity is 13 qts. Mix 2 gallons of our coolant with distilled water (50 to 70% solution) $48.00--good for 7 years or 250,000 miles. The only non-toxic and biodegradable coolant on the market.

Many thanks for what I assume will be a colorful array of responses, complete with intimate reliance on the Saxon side of our English Language.

Not by the advice of any amsoil salesman (I don't know any) but by my own prerogative when i got my 300 I filled up my diff with severe gear 75w-90, flushed the tranny with who knows how many quarts of amsoil atf (yes drained the torque converter too), flushed the ps system a few times with amsoil atf, and I was running the 5w40 cj-4 oil until I decided to switch to the series 3000 5w30. I use wix full pleated oil filters and I change my oil every 4 months regardless of mileage. (My car is my daily driver) When I was using the 5w40 I was changing every 6 months but it just seemed like the filter shouldn't be pushed that hard. I also change the trans filter and ps filter every 12 months just for good measure and it only costs a few quarts of amsoil atf to do that.
