So who is using a synblend / semi-synthetic oil right now ?
I've just changed to Penrite Vantage 10W40 semi-synthetic, and it's a very nice drop. Penrite claim all their semi-synthetics are a minimum of 20% synthetic (Group III) or more depending on product, and none contain Group I.
Previously I have used Valvoline DuraBlend 10W40 semi-synthetic, back when I asked years ago, it was 30 % synthetic. I've also used Castrol Magnatec 10W30 semi-synthetic, another excellent oil.
All three were rated API SN and Euro ACEA A3/B4 so they carried good specs.
I know the new GTX UltraClean is part synthetic, as are many of the newer "conventional" oils.
For Oz there is a real price saving going from full synthetic to semi-synthetic, but I realise some markets are different, and price the two so closely that it's easy to pay a bit more for a full syn.
To be honest, some of the smoothest oils I have used have been labelled semi-synthetic or synblend. I've never felt under gunned using them.
Anybody else using a semi-synthetic right now, or had good experiences using them before ?
