Report on Rykon oil for brakes

I monitor this site on Alpines almost every day but am loath to get into the fray, however, have been reading about oil used in the Fan, Power steering, and brake boost.

Several years ago the time had come to change the filters and lubricant. My choice was to install AMS oil ATF which I believe is a full synthetic but can't verify this. The noise in the steering quieted down and has remained clean with no deterioration in lubrication quality or braking.

Perhaps someone may have done the same. We now have 32K miles on our 03 Alpine. Mike E.

Sorry! I thought that you were the one that had supplied it. I would like to blame my poor memory on age, but it has never been that good about some things. Also, I didn't read your post correctly. When you said, "I'd like to hear your comments about this method." I was thinking that the method you described in the post was the one you thought that WRV recommend.

Due to the reasons that I posted and with the price of the Chevron Rando HDZ, I would try to do the WRV method.

Here's my latest 3 cents worth (with inflation) on the steering, brake assist and engine fan hydraulics. After reading all the posts on the subject, contacting Mark Harrah, talking with fellow Alpine owners that have switched to Rykon/Rando 46 and speaking with technicians at Chevron and Valvoline - here is what I did.

I drained the 4 gallons out of the hyd reservoir and what bled out of the return line, installed 3 new filters and filled the reservoir with automatic transmission fluid.

The Chevron and Valvoline techs said 15W40 (which my system had), Rando 46, power steering fluid and ATF are ALL compatible and can be mixed. They both said ATF, PSF and R46 are close in viscocity and that any of the four fluids can used in the system. One rep said since ATF has better heat and water rejection properties and (unlike PSF) can be found in gallon jugs he'd recommend using ATF.

I then ended up taking my coach to a local truck, bus, coach mechanic to have that #%& main fuel filter changed ( I tried every way my back would twist - from below, from the top, from the side, and finally gave up). The mechanic also said any of the four fluids would work fine and that they get motor homes, school buses and trucks with all three: ATF, PSF, 15W40 oil.

At the suggestion of other Alpine owners on the forum I had him change and flush the brake fluid. He used DOT4 which he said would stand up better to heat and rejects water better than DOT3.

It is probably my imagination but it feels like my brake pedal is a LITTLE easier to push - but that may be wishfull thinking...

After all this I have come to at least one conclusion....I told Carroll that if I EVER say I am going to change the oil. oil and fuel filters, lube, change the hydraulic fluid, etc. to tell me to look at the permanent mess on my RV garage floor, remind me of all the dirty shirts & pants I went through, the rolls of shop towels I used, the skinned knuckles and cut head and then go pay somebody the $ 300, or whatever, while I sit reading a book with a cool drink in hand....I USED to like working on my vehicles and having that satisfaction of knowing I could do the work - but I think I will try to replace that urge with the pleasure of signing a check or credit card receipt.

Harold, you're getting cranky in your old age. What happened to that passion for shedding blood while working on the Alpine. You might get Carpel Tunnel signing all those checks.
