Daveo26 Posted August 20, 2013 Report Share Posted August 20, 2013 I've been offered 25 litres of 5w40 fully synthetic oil is it ok to use this in my terrano? Some website recommend it others say mineral oil? It's cheap! Quote Link to comment Share on other sites More sharing options...
wraivi Posted August 20, 2013 Report Share Posted August 20, 2013 Should be ok. Normally if the engine is run in and everything bedded, changing to synthetic is fine.Couldnt say on the specifcs regaerding the sae ratings but if it is within manufacturers spec no problem I can tell. Just make sure you flush the engine with some cheap stuff good and proper. If you mix the 2 eveen in small amounts, after a week or so it will turn into a firm jelly when the engine cools. This cannot be moved by the oil pump so no oil circulation= oops! I speak from experience. Bought a used van and serviced it on arrival with manufacturer recommended oil only to discover a week later previous owner had used synthetic. When I dropped the sump pan, it looked like a jelly mould out of a fridge.! No harm done fortunately as no oil pressure on start up so off immediately and found the fault.

ditchman Posted August 21, 2013 Report Share Posted August 21, 2013 dont use it it is proberly recycled oil ...........fully synthectic oil is ussually very expensive.........the most expensive stuff is PTFE, oil....we used it on our snow blowers on the high speed diffs.....looks like milk.........incredible stuff......you mortage your house to buy it shop about for price....prices really differ Quote Link to comment Share on other sites More sharing options...
Daveo26 Posted August 21, 2013 Author Report Share Posted August 21, 2013 No it's not recycled its pukka decent new oil, my mate works in a garage and he's got it me. I don't know what to do now, the advice on here mirrors whats all over the net some say fine some say no. Milner off road sell fully synthetic oil for terra so and it's all over eBay...... Is it worth doing? ****!!!! Quote Link to comment Share on other sites More sharing options...
ferguson_tom Posted August 21, 2013 Report Share Posted August 21, 2013 Go for it the terrano engine is not a high performance engine so should be fine with pretty much any oil, might be worth flushing your engine through with a cleaner as if mineral and fully synthetic mix they can make a nasty sludgy mess. If you dont want it and is that cheap i will have it for my disco Quote Link to comment Share on other sites More sharing options...
