I need recommendations on what oil to use for my high mileage Vr4?Also I have a brand new transmission and need a fluid to handle the winter months as well as it does in the summer months. How often should I change it? :confused: I usually run Royal Purple in my camaro but some thing tells me that's just not going to cut it for the Vr4.
this isn't a recommendation but some inc myself use 20/50 in vr4's, some swear by royal purple.
if the car has lifter tick most oils will not cure it, the only way of shutting those up is by experimenting with different oil, but thats a costly way round it. i wish i could say thet 20/50 shuts them up but that never worked on sarahs. altho its a good thick oil and will give good oil pressure even in worn oil pumps, this i can confirm.
Rotella 15w40 is what a lot of people run, there was a huge thread on 3si about it, and the concensus was Rotella's the best.
I run redline 5w40,
how much is high mileage ?
180,000 miles and still runs strong without any engine leaks or noises...I just want to keep it running a long as possible
For the Rotella thing - I haven't run it in my car yet, but when I worked in a shop we carried rotella as our bulk oil. It was a private shop, so we serviced our companies vehicles only. Longest running motor on Rotella - 993K in a '92 Peterbuilt. Engine replaced and it's gone an additional 700K using the same oil.
I consider that a pretty good endorsement. I know CAT motors can last a long time, but a million miles on a single build tells me that good maintenance and good fluids/filters/etc had to play something.
Basically from UOA from the road course guys Redline 10w40, Rotella T Syn 5w40, Rotella T 15w10 in that order. That 5 million page mobil 1 sucks thread basically boils down to that.
For your engine i would suggest a 20w50 being high mileage, we run Brad Penn in all our cars its $6.50 (Not bad for a high end oil) a quart and hasn't given us an issue yet. You choice on oil that you can get though if you dont want to wait for shipping.
For your transmission there are only two fluids i would recommend.
1- OEM Diaqueen transmission fluid only down side is its $94 for a gallon and thats the only way to get it
2- Redline MT-90 thats what we use in all our race cars and street cars, works great, my tranny shifts like butter with it. Its also only 13.50 per qt (you need 3) so 1/3 the price of OEM.

Not sure if you are aware of it but Redline just released MT-85 which is the correct called for weight for the transmission. Since MT-90 is slightly too heavy.Quote:

I have been using rotella T 15w40 in all my cars for years and it does great.
I've been using Rotella T Syn 5w40 on my rebuilt motor unlike Mobil 1 on my old motor. Gotta love being able to get it cheap at Walmart. Of course I used conventional oil for the break-in.
makes sure it has GL-4. I love the amsoil.
I have not tried the new redline, so I can't recommend it yet.
right neither have I. However i have mixed MTL and MT-90 in my car now which should yield something very close to the MT-85 and its a lot better than whatever was in my trans before.
I use AMSOil lubricants for everything. I've used them since 1979 in drag cars, street cars, motor homes, tow trucks, you name it. I have ALWAYS had superior results. LMK if you're interested.
Blindmist said it correctly. Only use GL-4 in our transmissions.
GL-5 oils have a high sulfur content that gives them extra pressure guard. BUT, that extra sulfur content eats up brass in the transmission and it just so happens that the syncros in our transmissions are made of brass. You can do your own math on that one.
Just make sure it's GL-4 rated.
I'm switching to Brad Penn 10w-30 with a Purolator PureOne filter this week. I know Brad Penn is all Chris at 3SX runs in his monster DD, but Rotella is definitely good stuff too.
I've been running Rotella T 5W-40 in both my '97 VR-4 and my '98 GSX for a couple of years now. Amazing stuff. Looks better after 4k than the Mobil 1 that I used in my VR-4 when I first bought it after 2.5k.
Redline MTL/MT90 cocktail. I didn't hear about the MT85 but I'm guessing I'll try it next time my trans gets dropped... which will be next season the way my luck goes.

Seriously, this is some of the best stuff for our transmissions.
Purelator PureONE is the best oil filter on the market too btw. Nothing has come close to the 99.9% filtration of a PureONE.
Since you have a TT i would suggest going with 40 weight instead of the 30, also use the OEM filters their only 6 bucks and really good. I like the fact that its only $38 for an oil change that way.Quote:

Have any UOA to back any of that claim up? If not you don't know if that oil was good for you or not.
I've been a 'cocktail' user as well for the last 9 years. Next change I'll use the MT-85. I just recently learned this new line existed!Quote:

Just ordered 5 quarts of mt85 for the smurf and daily driver. Ill report back next week.
I've always heard the general consensus was to never use fully synthetic oil in a high mileage engine if you've been using a non-synthetic oil. Synthetic oil, being thinner than regular motor oil, will find oil leaks where none was before. Is that fact or fiction? :confused:
I just got my MT-85 in the mail the other day. I'm going to be doing a drivetrain fluid change this weekend when I drop the trans. I'm hoping it will greatly improve my notchy shifting issues that I have been having ;) Also throwing in a new OEM fork, pivot ball, and slave cyl for good measure while I'm at it.Quote:

Rotella T Syn 5W40...hands down. I ran 2 track days with oil temps at 260* (2 hours on track a day) and had no issues. Oil pressure was still good the whole time.
I use Syntec 20w50 and it keeps my oil pressure up for a couple thousand miles, but with as many miles as I have, I like to change the oil @1,000 miles which is pretty often, but I always know I have good oil, and I don't leave it in long enough for any to burn off... My shifter is really notchy with a bad 2nd syncro, so I always have to shift slooooow, LOL! I'm gonna try that MT-85 and see if it helps...
