Shan,

I have oil consumption issues with Double Trouble that appear to be speed
related. I use Shell Rotella T 15-40W and if I drove 55 - 60 the consumption
was nil. If I raised the speed up to 70 the oil consumption went up
significantly. I don't have any specific figures as all I'd do is fill it up
to the dipstick line and no I haven't calibrated the dip stick.

I wanted to switch over to synthetic oil to see if that made a difference. I
had a chat with the local NAPA manager in Humble. He suggested I consider
using single viscosity oil and noted that Royal Purple (and one other
company that I can't remember) made single viscosity synthetic oil. RP goes
all the way up to SAE 50. I decided to go with SAE 40 for Double Trouble
which I put in before I left the USA. Stay tuned to this channel and you'll
find out what happens NEXT SUMMER!

Pricey is right - list was over $9 a quart but because of all the parts John
Sharpe and I buy from this store he sold it to me for around $7.

Regards,

If you guys are still worried about Zinc then run Royal purple, RP kept its
SL certfication and still has ZDDP in their oil. RP is a bit oricy but its
great stuff...

you are aware that it takes some time for all the oil to run back to the pan so when you stop for gas your oil will always read low for about 20 minutes.
