Thread: low oil pressure on startup?

It may be oil related more than filter related - a ryco z9 is fine if it gets changed regularly.

Strange as it sounds the 3.5 RR in my 89 prefers 15w40 rather than 20w50, which is what HPR30 is (According to their website anyway).

It's more to do with temp and work rather than wear. If I was operating in temps 40 and above and towing stuff, the HPR30 would be the go - in cooler areas HPR30 could be too thick for the Range rover engine.

You'd expect a 20 yo engine to need thicker oil - go figure.

some filters have a drain back valve in then to keep the oil filter full of oil for the next start up. this shouldnt be an issue with the rover V8 filter cos of how it sits in, ie holds oil cos its pointing down. ive never used a fram so i cant comment on them but ive used countless ryco's and coopers with many types of oil and have never had an issue.....till the oil pump pressure relief got stuck

$40 . Your dealers have a bigger mark up than ours.
Full tilt here is under $20, even less if you have 'contacts' .

and they can be fitted to morris minor one billions! along with countless ''other'' LR parts...

I also think the oil is just a bit too thick when cold, so takes a while to get thrown around the engine.

You may also notice the engine is a bit more rattly at startup and until up to operating temperature, again due to the more viscous oil when cold.

Not sure about the ambient temps in Auckland, but a thinner oil especially thinner when cold might be the go.

I would also expect it to get worse in winter when the temp drops.

Hi.

Thanks for the advice re oil filters. I will try a different oil.


Much appreciated!
