Oil change concerns..Air filter?????

[VXNIT]

I went to Isuzu for quite a while for changes aand decided to stop and do it myself several oil changes ago. I used Valvoline 5W30 lst change adn decided to go with Castrol GTX 5W30 this tiem and the oil was like water. I am thinking how is this going to protect engine parts??????? What is best oil for our VX??????
Also I am running stock filter would fellow VX'ers reco upgrade to K/N or Tones????
How much is K/N. Tones are 69$.....Thanks folks..

I switched to Mobil 1 0W30 at the dealer's recommendation @3000 miles ago. It has quieted down the motor and increased the fuel economy. I am very pleased with it.

I notice that my VX seems to have quite a "clicky" motor, probably valves, specialy initial starts. Did you go with synthetic oil or reg Mobil 1??

Go with the Mobil 1 (or equiv.) synthetic...it's the only way to go with oil. I use it in the VX and the Rodeo and it makes all the difference in the world. A quiet, smooth running motor. Also use a good Fram oil filter. Stick with the best and you won't have any problems.

I just switched to Mobil 1 synthetic on my last oil change. I used 5W30. What is the difference between 5W30 and the 0W30 mentioned above? I don't recall ever seeing 0W30, could he have meant 10W30? Any knowledgable feedback would be appreciated.

Thanks,

Just started doing mine myself and used Valvoline 20W50 and what a difference. I was getting valve noise and the power just seemed a bit off, you know the car just felt wrong, but after the switch she feels GREAT. I have about 57,000 mile on her. I switched to 20W50 because with my motorcycle as the weather gets warmer you us a heavier oil and if you look at the owner manual for the VX there is a chart on what temp range goes with what oil. Even when I was not doing the oil change my self I would always tell who ever did it what to use. For example in the winter 5W30 in the summer 20W50.

I meant 0W30. It's a slightly lighter weight than the 5W30 that you mentioned. Essentially it's a 30 that'll flow like a 0 when it gets hot. It's not going to be very common in the southern states, where cold weather isn't so much of a factor.

My "clicks"..especially at starts...were the result of a loose EGR valve..as pointed out by the local dealership. I tightened it and the clicking went away!

[blacksambo]

What's an EGR valve and where is it situated in the engineroom? (Please pardon my ignorance but I'm new to VX but a long time car hobbyist.)

[Ldub]

EGR (exhaust gas recirculation) is located (standing in front,facing engine) on the left side towards the rear of the cylinder bank.The tube from the exhaust is held on from the bottom with a 22mm nut that you need a stubby open end wrench to tighten.
Search site for EGR for more exciting info. on cleaning etc.
