Car Forum / Volvo Cars / March 2005Oil
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 >Okay, > [quoted text clipped - 5 lines] >What is the best type of oil to put in the lump? Semi-synthetic or synthetic >and also 10/40 or 15/40? 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.

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.

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. Mike >>>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 [quoted text clipped - 20 lines] > > Mike 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 >> No, please! We've seen this myriad times here and other places! It never >> goes anywhere.

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/groups?as_q=synthetic+or+dino+oil&num=10&scoring=r &hl=en&ie=UTF-8&as_epq=&as_oq=&as_eq=&as_ugroup=alt.autos.volvo&as_usubject=&as_ uauthors=&lr=&as_drrb=q&as_qdr=&as_mind=1&as_minm=1&as_miny=1981&as_maxd=14&as_m axm=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".

[quoted text clipped - 9 lines] >who expressed that he had worked on a similar model that had used synthetic >oil and the throttle body didn't have the deposits. 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.
