Is there anyone using Delvac 5W-40 oil in a 1HZ. I've always used Delvac 15W-40 but have acquired some 5w-40 fully synthetic. Being an older design engine I was just curious if others were using it in this motor.
Regards Jon

Hi Jon

I use Penrite HPR diesel 15

Bringing you the latest in light duty diesel oil technology, this semi-synthetic is suitable for most modern direct and indirect injection diesel engines including turbocharged. Ideal for new diesel vehicles under manufacturer’s warranty and normal driving conditions. Some vehicles may require Enviro+, HPR Diesel 5 or SIN 5.
SAE 15W-50, API CH-4/SL, ACEA A3/B4, M2C153F/G, Global DLD-1/3, VW 505.00

i changed to this after i Turbo it good stuff but im telling you your opened up a big can of worms on what oil to use
but what ever you use change it every 5000kms

From what I understand, provided that the oil specifiications meets the requirements of your motor, the lower weight of 5 moves around the engine much better when cold (as opposed to a 15 weight.....less wear at startup with the lower weight), and when its warm the weight is 40. A chemist for Castrol told me this.

Theres a million people out there with 1Hz Toyotas and nobody with a 1Hz has answered your post. I expect that means (and I reckon its true) that no one would waste an expensive oil on an immensely reliable old motor. These thing don't wear out on standard oils, so no point in going to synthetics. If its anything like my daughters 1Hz, it goes black in no time after a change from all the soot. Would be a shame to see $100 worth of oil go dirty straight after a change. We use 15W40 diesel engine oils with out LandCruisers - have done for as long as I remember. Never worn one out.

Thats about it - I use 15-40 whatevers cheapest without going repco brand - but heck maybe that would be ok too

any way usually its shell or castrol about $45 for the 10 litres but i think it might have gone up
