I have bumped this from the oils section as I did not get any response, I appreciate any thoughts as it really is oil change time!!
I have ran all winter on Toyota's own brand 5W30 semi synth as recommend/supplied by my local Toyota dealer.
My LC 100 diesel with 160K has not used any in the last 6000 miles still on max on the dipstick, no top ups.
However I noticed some slight oily residue in the turbo inter-cooler pipe the other day obviously its not much as I have not had to top up in 6K.
The under bonnet sticker says 10w 30 IIRC, is running on the thinner 5W 30 as recommended by my local Toyota dealer still OK?
It states that it is fuel efficient oil on the can!
Or should I now go for something a bit thicker for summer such as a 10W 40 considering the mileage and slight turbo oiling?
