Oil recommendation for light track use-but hot weather.

emotionr

I just got my ride (2010 roadster), and will have to consider getting AMS OIL 5w-30.
I live in Texas, HOT in summer, so hopefully this will help or prevent any issues.

I have a '12 an added a 25R oil cooler and switched to Valvoline 10W30 VR1 Racing Synthetic. So far all is well. I, too, daily drive mine and will be doing occasional track events.

Spirited flogging through the twists so far has gotten me no more than 215 degrees. It isn't tracking but I'm still finding it very difficult to get the temps over that point. Combination of the stock cooler and an outboard cooler seem to be pretty good. Just try not to go on long drives without a cover. No oil consumption to note yet either. And the slight ticking I had has gone away. I can still hear the valves and cam doing their thing but no ticking like I heard with the stock fill.

For track you are looking for a very shear stable product. Folks have mentioned a lot already and I think all of them would do you fine (M1, Amsoil, Motul, Redline).

If you are looking to have extended oil change intervals as well (since your track time is not that frequent), you want a product that has a good additive package as well. To me, that would mean looking at M1 0/40 SN (Wally world has it now in 5 quart jugs...winning)

Redline would be a bad choice for extended OCI's: great product for shear stability but not the best add pack even on their street synthetics (not talking about their pure race products...which is race only really).

For a street oil, Pennzoil Ultra is also an excellent product and their 5/30 has been showing very good UOAs on our Z (PA, 90+deg humid summer days) and I wouldn't hesitate to run that at a track event either.

Oil is over rated!

Nice post. I will be trying the Penzoil at the end of the summer when service is due!

There is more than one Mobil 1. There is the normal auto parts store version and there is also Mobile 1 4T which is targeted at high performance sport bikes and auto racing. The 4T is about double the price of the normal consumer Mobil 1. The Mobile 1 MX4T (as it was called then) is the oil I saw stacked up in cases in the pits of Texas Motor Speedway during a NASCAR race a few years ago. So I believe that could be the version of Mobile 1 used in big time racing. It appears to be available with API ratings of SM (small quantities of extreme pressure additives) and SH (larger quantities of extreme pressure additives).

Here is a link to the Mobil 1 4T product page: Motorcycle Oil | Mobil 1 Racing 4T™ 10W-40

DON"T! use motorcycle oil in your car! 98% of the motorcycles out there have a wet clutch in them. Meaning that the engine oil is also the transmission oil too. and the clutch is bathed in it too. So the oil designed for that type of set-up has different elements in it. What's good in a car engine, is not good for the clutch plates in the bike. Over time the clutch will slip. So what's good for a bike, is not that great for a car motor. I'm keeping this simple.



Mobil 1 Racing 4T 10W-40 is recommended for 4-cycle motorcycles which specify the use a 10W-40 engine oil. This oil will help provide excellent performance in motorcycle engines that are designed with a common engine/transmission lubrication system or where the engine lubrication system is separate from the transmission system. In the case of the latter, follow the manufacturer's recommendation for the type of fluid to be used in the transmission. Mobil 1 Racing 4T 10W-40 engine oil is designed to help provide the proper frictional characteristics necessary for wet-clutch common engine/transmission systems. It has been fully tested, both on laboratory dynamometers and in the field, to help provide optimum horsepower and acceleration

while the "series" might change, this has been a good rule of thumb for awhile. from best to worst starting points of oils...(not all shown). oil reports will tell what "annihilates" the competition.

The best base stock is Polyol-ester (Redline & Motul)

Next best is Di-ester (Royal Purple, Amsoil, Neo)

Next is Polyolefin polyamine (Mobil 1)

Next is Hydrocracked (Syntec, Valvoline)

And finally, regular dyno oils.

Motul has a 0w40 that is specifically recommended for the 370z. It's about $60 for a 5 liter jug... (5.1 quarts) Just enough for a complete oil change (if you don't have an oil cooler). I'm trying it this weekend. Motul makes all of Nissans oil. Including the super duper Estér Oil.

ok im a little confuse now after reading all this thread hahaha!! I use Mobil1 synthetic oil 5w30 Extended Performance since I buy my Z.... I would use Amsoil or even Motul but to find those oils here in Puerto Rico is very difficult Well I use my car as my Daily Driven and some sprinted or track days sometimes... My question is... If I change now to Mobil1 0w40 they are going to work better than the 5w30 that is the one recommended for Nissan to our engines? the temps over here are arround 70+ to 95 degrees and in summer on a very hot day you can see temps on 100 degrees

Any help or recommendation are welcome... BTW the oil cooler are on my wish list as soon my new damn wheels arrive someday

Thanks!

Rusty

I run the Mobil 0W-40.No problems.
