Oil

[Richard Setford]

Okay,

I've had the thing a week now so it's time for a service.

Just as a reminder for everyone, we're talking about a 1990 740 SE 2.0i Auto
Estate.

What is the best type of oil to put in the lump? Semi-synthetic or synthetic
and also 10/40 or 15/40?

Thanks,

Richard

I'd doubt there'd be much benefit in using synthetic if it has not
been used up till now.

I use Castrol GTX in my '87 740. They do a version for high mileage
cars now, though I'm not sure what the difference is, and it doesn't
seem to make much difference to either oil consumption or fuel
economy.

15W/40 is fine for UK use, unless you are in the north of Scotland in
winter, where 10W/40 may be better.

I'd also be happy to use Duckhams, Silkolene, or any other well
established quality oil.

Thanks for that. I've used the Castrol High Mileage stuff before so if
it's been okay for you, I'm sute it'll be alright for me.

The last couple of cars I've had have been more 'performance' cars so I
guess that's why I'm a bit biased towards sythetic oils.

Not wanting to restart the synthetic oil controversy, but I changed to
synthetic in our '85 765T because I was tired of the deposit buildup in the
crankcase ventilation and engine induction system. IIRC it was a guru here
who expressed that he had worked on a similar model that had used synthetic
oil and the throttle body didn't have the deposits.

Okay, that's thrown a spanner in the works!

Right everyone, we'll sort this out the old fashioned way.

Please cast your votes for either sythetic, semi-synthetic or 'normal'
oil here. No debate (just yet), just votes for now.

Thanks,

Richard

No, please! We've seen this myriad times here and other places! It never
goes anywhere. We can each make our own choices - we don't need to identify
a "winner" or "loser." Now I'm sorry I even mentioned it.

I think you are right that synthetic oil won't leave deposits like
mineral oil does, but I have heard, anecdotally, that if you switch
from mineral to synthetic, the old deposits in the engine can be
softened and break away, leaving you with gallery-clogging sized bits
of crud floating around in the oil. This is not desireable.

My feeling is that on a car of this age, switching to synthetic is not
really going to prolong its life more than regular changes of mineral
oil, so the price difference cannot be justified. Good quality mineral
oil, used properly, has seen a great many Volvos achieve high mileage.

Don't be like that Mike.

This is a new area for me and I just wanted to get a balanced opinion.
I'm not after a winner or loser to go 'ner ner ner ner ner' at, I just
want the best for my car.

What's wrong with that?

I hope you can see my point of view,

Richard

I can see your point, but I can also see Mike's. So here's what you
can do. Google has an archive of this group. The archive is
searchable. I have attached a link to previous discussions on the
same topic. Opinions haven't changed since then, and we won't have
to go through the rigmarole of pissing on other people's opinions
once again. Here's the link - good luck with your decision:

<http://groups-beta.google.com/group...1&as_maxd=14&as_maxm=2&as_maxy=2005&safe=off>

In case the link is too long, here is a TinyURL of the same search:

<http://tinyurl.com/4bhgd>

And if neither works, the search term was "synthetic or dino oil" using
Google groups, and restricted to "alt.autos.volvo".

Good thinking.

I'll try that. the last thing I want to do is annoy anyone

Why dont we all use Amsoil and support the cult !!

 

[John Robertson]

I am using B.P synthetic oil because I want our 3 Volvos to last .2 are
turbos so its a must for the heat and wear tear .Its costs to replace a
motor We are using 5-40 @ 300k 240k and 160 k no oil consumption no oil
grunge build up .As for the Amsoil cult ,we dont have such oil here,thank
goodness. Too much hype .

 

[John Robertson]

When old faithful gets weary why put thick oil in the old dear ,its too much
and will speed up wear on start economy will suffer ?give it a genuine
synthetic oil change clean filter and what the machine clean up fast .The
old dino oil will glug up the system so expect a lot of nasty stuff to come
out till it cleans up after a couple of changes .remember filters filters
and quality oil

 

[Andrew Potter]

I think the issue should concetrate on the correct API spec of oil for
the specific engine. Any oil that is certified for the correct grade is
deemed worthy, be it synthetically-based or a blend.
