Exclamation Put Mobil1 in my R1 for the first time

On the advice of Gordon Monsen, Chuck Westbrook, Dave at KD Rotary (second hand) and various others I changed my oil two days ago and rather than fill it w/Valvoline VR1 Racing 20w50 like usual, I put in 4 qts of Mobil1 15w50. Results were (and are) immediate. The car runs much smoother, accelerates and decelerates noticably better. Quantifiably, by the Power FC Commander, my Water temps decreased by ~4-5 degrees Celcius in all conditions. Idling, cruising, revving her out. Nothing else has changed; it's still hot as hell here in TX, so that's not a factor . I'm definitely happy with it, I'll keep you all posted.

Also fyi, I had just changed the oil less than 1000 miles before; the oil that drained out wasn't even dirty.

Btw, how often to change? I'm planning on every 3k miles.

AAAAAGGHH!!

I use Redline, it's moooooch better! You need to use Redline too. You can mail order it, they offer discounts for multiple cases.

Step up to a higher plateau in engine oil, REDLINE.

The car is red, the oil is red, it only makes sense.

I'm sticking with Neo for a while. I've heard its better than Mobil 1, Redline, and all other popular synthetics. Even their non-synthetic is better than most synthetics.

I've been running Mobil1 Snyth. for 3 years now, I change mine every 1000 miles or 2 months which ever comes first ( but I get the oil free at work), U might not want to go 3k cause of gas dilution. It's your call.

here's a question:

is it okay to switch brands of oil? i've been using castrol synthetic, and i want to switch to mobil1. I know some old oil will be leftover when i drain it, so is it okay if a small amount mixes?

There has been alot of info about synthetics being bad for the rotary engine. The high flash point of synthetics makes it gum up inside a rotary engine. Due to the rotary using an oil metering system to lubricate the apex seals the synthetic doesnt burn like conventional oil and causes premature failure in the Rotary. Although synthetics are great for turbocharged cars in general due to the high temps its been a general rule to use conventional oil in our cars and just chage it frequently. I know under high boost and heavily modded Rotarys its still recommended to use synthetics because the benefits out weigh the potential problems. Highly modded engines rarely see the same longevity as stock engines so build up with synthetics isnt really a factor. I am suprised no one has brought this up on this thread. I would love to go back to using sythetic oil if there hasnt been any documented engine failure due to its use in the rotary.

my opinion re synthetics, based on some research I have done, including ASME journal articles (my bro works for advanced vehicle engineering at GM)

for very high revving, high load, or extreme temp conditions, synthetics work great and are likley worth the $$$$...if you operate your car under somewhat "normal" conditions (street driving) they are unlikely to add significant life to your engine, vs. a quality petroleum oil (I personally use Castrol 20w-50, which is what Pettit recommends, aside from synthetic)

it is a common myth that synthetics are "long drain" oils that can go 5-10k miles on an oil change...absolutley untrue...they still accumulate dirt and metal particulate (which causes excess wear) at the same rate as a conventional oil.....particulate saturation occurs at roughly the same mileage interval (about 3,000 miles for n/a cars) for any oil....turbo cars dirty their oil MUCH faster than an n/a engine, so I think 1,500 miles is a good interval for hard street driving

as far as which synthetic is better? think about it, quantity means lower price, and there are WAYYY more people using Mobil 1 than either Neo or Redline...not saying those are not quality oils, but as far as the difference between them and Mobil 1, I don't think there is much, and Mobil 1 is about 1/2 the price
Boy howdy, do I think you make sense.... I am an FAA Certified Mechanic, and I can guarantee you that changing your oil at 1500 miles intervals (no matter what brand, syn or non syn) will make your engine last practically forever. I like straight 30W since I live in a mild climate. Our Rex engines are EXTREMELY dirty oil injected engines, and dirt equals accelerated wear! $15.00 worth of oil and filter instead of a new engine? My $.02 cents worth... (that's why we have specified intervals in airplane engines, some as short as 500 hours of service - it's proven to make them almost bulletproof and never have oil related failure problems, and yes, I have lots of experience with turbo aircraft engines... that's why I love my Rex!)

Hey GoodfellaFD3S, I don't know why it would or wouldn't affect this, but did your knock figures change at all before and after the oil change?

I find all this very interesting but would have to ask "why do synthetics work better?" I mean the oil is injected and lubs the turbo bearings but what else? I mean it must be reducing friction somewhere to create such a difference... right? I would like to start using Mobil 1 but only if I understand why it is better in a rotary.

Has anyone ever tried a "synthetic blend"? I know Castrol makes one and might be the answer for those that don't want a full sythetic.

Thanks for the reply Gordon. I am tempted to go back to synthetic. I love the stuff but have been scared for the motor. The turbos could use the high flash point. I am not always good at cooling it down before shutting it off. No turbo timer either.

I used synthetic blend type oils in my boinger for several oil changes until I discovered that the amount of synthetic that they use in the blend is almost insignificant. The stuff is mostly (almost complete) conventional oil, with a tiny bit of synthetic. It's not work it. Castrol GTX is about $1.40/qt. The synthetic blend stuff is between 3-4 at the local auto store. Mobil 1 full synthetic only costs something like $3.50 at Costco. Not really cost efficient if you ask me.
