The 95 Coaches Do Use Different Oils According to Engine Type

The 95 coaches do use different oils according to engine type.

The 8V92 uses an inline fitter in addition to the 3 reservoir filters

Parker Canister filter-(about 18" long in line street side), ( according to BB somewhere between the radiator and the tag axle).

Reservoir filters All models, ( 8V92 & Series 60), use the same reservoir filters.

The reservoir takes 3 filters.

The 8V92 uses 10W30, synthetic oils are ok to use.

The Series 60 uses HD32. Synthetics are OK to use. BB cross referenced the recommended Dino. oil with CASTROL VS977 Synthetic. I can’t find it online. Waiting for return call from tech service.

After lots of surfing today I have found out that HD32 is a Texaco product, Rando HD 32. As of July 2008 Chevron has the Texaco label and will continue to mfg. The Rando line of fluids.

I also learned that any oil that is equivalent to ISO 32 should work in the system. Some of these oils have a , AW or O&R rating. Anti -Wear and Oxidation and Rust. Some have a combination of prefixes. There are also biodegradable oils for Forestry and Marine applications. I would recommend staying away from these because they generally have a shorter service life. It your call. I will most likely stay with the Rando HD 32 or it’s synthetic version

I know all oils are not created equal. The mineral based oils run anywhere from $30 to $60 for 5 gallons and the synthetics are $120 and up, some way up. The blends fall in the middle.

The capacity is 16 Quarts for the series 60 and 18 quarts for the 8V92, Jessie recommended buying 5 Gallons just to make sure you have enough to refill the system.

In my opinion I would think capacity would be determined by how well you can drain the system of old fluid. So I don’t think these numbers are written in stone in this senario.

To drain the system BB has a vacuum system that evacuates the reservoir. They do not recommend disconnecting any of the hydraulic lines in fear of creating a leak or breaking any connections, especially the elbow under the reservoir tank, I can understand that, the line and elbow are quite a bit heavier construction than the tank, and BB has encountered breakage at that particular point according to tech services.

Double oil and filter change

This technique involves an initial oil drain and filter change, The system is then filled to the minimum level required and the fluid circulated until operating temperature is reached and the fluid has been turned over at least five times. The oil is drained and the filters changed a second time. An appropriate oil analysis test should be performed to determine the success of the flush. To maximize the effectiveness of this technique, the system should be drained as thoroughly as possible and the reservoir mechanically cleaned.
