Mixing oils
I use Fuchs Titan XTR 5-30 in the Landy and in the wifes Focus. I have 3l left in the tub from the last batch.
A mate works for a car spares chain and can get Carlube 5-30w for a cheaper price(which is fine) but, he suggested I just mix the Carlube oil with the remaining Fuchs oil and off we go.

I'm not sure about this as mixing oil from two differing manufactures doesn't get my vote, hence I have purchased a new drum of 20l Fuchs.

So peoples thoughts on mixing oil makes of the same 5-30w spec? 1999 Defender TD5 110

In my cheap run around (which has a few minor leaks) I put in different grades & brand whatever is close to hand. Does not seem to make any difference.

Wouldn't do it in a more vaulable car (or my Defender), as I am too OCD!! Mixing different manufacturers, but same grade (+ not mixing mineral, semi, fully synthetics) should be OK as the difference should be down to the additive. If there was a major problem with doing it, I guess it would have cropped up somewhere in the media before.

Years ago I had several series Landrovers and an old Marina van that used to use oil so that it required topping up every week or so. At first I used the cheapest 20/50w i could buy to top up with but ended up putting EP90 gear oil into them as I found that it took ages to need topping up again! No adverse effects on the engines as I ran them for years like that! Wouldn`t recommend you did that with yours however! Laughing
