Discovered this site by accident recently - too much good reading - work is suffering!!

Anyway, would welcome comments on oil pressure for a 95 Troopie (1HZ, nominally 140,000k, but some doubts about early life history!) - had it serviced just before Christmas, not in my normal shop, and they put in Magnatec "10W30" according to the sheet. Since then the oil pressure is showing lower than normal - not dangerously but noticeable.Also, the oil change sticker has next change for both filter and oil shown at 10,000km. Castrol website says 1HZ should use 10W40, with no mention of a Magnatec 10W30. Spoke to Castrol who said the 10W30 is a 'special brew' for service sations ("one size fits all maybe" ?) and I had the definite impression they were not too keen on using this in the 1HZ though not specific.

Should I change now to eg Caltex DELO400 or Penrite HPRDIESEL, or live with it until next oil change (which I intend to keep at 5000km) in a month or so?

I'm no mechanic - but with such things - I'd be conservative and go ahead with another oil change. Cheap insurance for my mind...

the last thing you want is to cruise around for 10,000 km in a diesel with the wrong oil in it. Get it out of there and use the delo400. I found that castrol's RX Super always performed OK as well or Shell rimula.
Best to be safe than sorry.

Gday Rob,,Havent heard of the Magnatec stuff. I doubt you would do any damage to your engine if you left that oil in for 5000Km but as has been mentioned it would proberly be best to play it safe. If you used the Penrite HPR Diesel I would garentee you will get a better oil pressure,its a bit more expensive but good stuff. You are also correct about the 5000Km service interval for a diesel also with a new filter. With a Diesel or any engine for that matter the three rules are clean oil fuel and air and you have it covered. (Retired Diesel mechanic)

We've had IHZ powered Tojos here since they first came out, and have always used Shell Rimula X 15W/40, and have never had a problem. Admittedly our vehicles get changed every 3 or 4 years, between 150K & 200K clicks.

Have also been using this oil in our private vehicles too, for at least 20 years. For the price, it's cheap, but does a good job.

Do 5K oil changes, but only change the oil filter every 10K, along with the primary fuel filter.
Hope the "early life" of your tojo isn't catching up to it.

I fully agree with Bob Y. Been using Shell Rimula X 15W/40 for years with oil changes every 5k. Never had a problem with low oil pressure readings. Cheers.Have Wheels Will Travel

Many thanks to all for your comments. Will be doing an oil change this weekend.
Suppose it just goes to show that if you want anything done right "do it yourself"!
