Car Forum / Nissan / Nissan Z Cars / October 2003Running 20W 50 Castrol Oil in my 350-z
My oil pressure is pretty high. Almost to the end of the gauge. Is that where it's supposed to be? don't listen to people trying to insult you when you ask for help. that is not normal. just go to your dealer. should cost 40 bucks. maybe 80 no more than that. they will take all that out. and replenish. cool? peace. > My oil pressure is pretty high.

That is what the manual calls for but to answer your question NO the gauge should never be that high and I would have it checked ASAP! Ny > My oil pressure is pretty high. Almost to the end of the gauge. Is > that where it's supposed to be? What did you do? Change the oil? Must be an idiot. You're going to blow the engine. The oil in that car should be thin like water. I hope you live in Death Valley. 20/50 is a pretty viscose (thick) oil. I used it in my air cooled motorcycle during the summer months. In the cold morning it is like mud. That is why your gauge is so high. Your gauge should come down a bit once the engine is hot. I'm pretty sure the manual does not call for it. Should you burn your motor up with it in there, your warranty will be voided. It's not worth the risk. Randy > My oil pressure is pretty high. Almost to the end of the gauge. Is > that where it's supposed to be? get that 20w50 oil out of the engine NOW !!! you should be using 5 or 10w30 > My oil pressure is pretty high. Almost to the end of the gauge. Is > that where it's supposed to be? Why did you put that oil in your engine ? Get rid of it immediatly ! Put at least 10W30 or 10W40, better 5W30 or 5W40. Mobil 1 synthetic 5W40 should be perfect. > My oil pressure is pretty high. Almost to the end of the gauge. Is > that where it's supposed to be? Used to use 20/50 in my 64 XKE years ago and a 454 Vette in the 60s. Use 5/30 in my 01 Prelude. Most of the new engines have very close tolerances and require anything from 5/20 to 5/30. You will likely ruin the engine, if you have not already. > My oil pressure is pretty high. Almost to the end of the gauge.

Nonsense. The manufacturers recommend 5W oil in the manual, because they know that this "water thin" oil will torture your car's engine, but will still enable the motor to last just long enough to to void your parts warranty before the engine blows. In other words, they are counting on you having to pay for a new factory motor so they can make some extra bucks down the road. My 1989 Camaro manual also recommends 5W 30, but I don't think it would do the engine much good seeing that the oil pressure at that viscosity barely moves the needle on the oil gauge! > Used to use 20/50 in my 64 XKE years ago and a 454 Vette in the 60s.

You will do more damage with 20W/50 once winter weather sets in do to the time it takes for the oil to flow. I have a 1993 300zx with 150,000 miles running 5W/30 oil. > <Most of the new engines have very close tolerances > > and require anything from 5/20 to 5/30.

I run Castrol 20/50 in every vehicle that I've owned. Have had no prob. The oil holds up longer than the lightweight oils, and the vehicles perform better once the engine reaches operating temp. It may not be best during winter in the colder regions, I'm in N.C., so no prob here. Years of the vehicles are '83 through '99. > The 5W refers to the viscosity of the oil when cold during the winter.
