My oil analyses on second oil change of Plus 4 best ever in 700 hrs.

If you are now consuming 1.0 oz of oil per hour in your 912UL (490 hours TT); if my calculations are correct that would be just about 1.42 liters of oil consumption in 50 hours!!!! (normal oil change time for a 912). That to me is excessive oil consumption. I have a 912 UL on my Allegro 2000 with just about the same amount of hours (480 hrs). I use Mobile1 4T Racing oil (from the beginning) and have never had to add any oil between oil changes (50) hours. Either my math is wrong, or your number is wrong. A 912 should not consume oil at that rate at 490 hours. Hugh G. McKay III, P.E.

For the guys that need a semi synthetic I will recommend Golden Spectro 4 motorcycle oil (10-40W or 20-50W) It has been around for a long time, rated high and has been tested in high rpm, high performance motorcycles for many years. -------- Roger Lee Tucson, Az.

Then he has unexpected maint and early gearbox repair and gear wear at 400 hrs.. His engine is using oil. Rotax says if an engine sits more than 2 years to replace all "O" rings through out the engine and who knows how it was started and taken care of the first couple years of its life. I think Dashwood has some mechanical issues that started right up front and if he is still using oil they are continuing issues. Sorry Dashwood, but there is a root cause and problem here. -------- Roger Lee Tucson, Az. Light Sport Repairman - Maintenance Rated Rotax Repair Center - Heavy Maint.

Most of you don't have a 1000 hrs on your engine or haven't used Aero Shell for at least 500+ hrs and disassembled your gearbox for an inspection. So how would you know? The 800ppm is the same as car oil. So why aren't you using car oil? The answer is because you thought Aero Shell had the correct levels of additives. You can use car oil in your Rotax too and won't know about the extra wear until later in the game or when the gearbox is stripped down for its 1000 hr. inspection. Then it's too late. Some of you have that symptom with a squeaky gearbox. That is just one sign that you are metal to metal and unprotected. I got my info from the top sources in the industry. I would find it hard to believe they don't know what they are talking about when they have the exact numbers and leaders in their field. You are right that I have not tested this oil, but the down side is too expensive for too many of my clients. I put this info up so everyone can make an informed choice and by no means am I telling any one what oil to use, but it is buyer beware. For me and my clients I think playing it safe until the reformulation comes out next year is a safer plan. Gearbox and engine parts are too expensive to take this chance. I look at it this way, If I'm wrong I have not cost myself or my clients anything other than a change in oil brands with a known proven and tested oil, but if I'm right I just saved all of them a pile of money. Aero Shell hasn't been out long enough for actual field results and they are already talking reformulation? -------- Roger Lee Tucson, Az.

How have you been? In the air much? Come on over to Ryan and I'll buy you breakfast. You should come to The Page, AZ Fly-In this year too. We have some others that fly your cruise speed. We may have sold out on reservation, maybe 1-2 rooms left. Give me a call. One issue with Aero Shell with me is, when a company with as little time on the market as Aero Shell Sport Plus 4 has and then they say they are going to completely reformulate (new base stock and double the ZDDP), well that has my full attention as to why they think they need to completely re-formulate their own product. -------- Roger Lee Tucson, Az.
