Want to know If I can safely use something like full synthetic Chevron 10w-30 oil with full dino 10w-40 like Castrol GTX or even just Castrol synthetic mix.


Ok so:

2x Chevron full synthetic 10w-30
and
2x Castrol GTX full dino 10w-40
OR
2x Castrol synthetic blend 10w-40

I drive hard sometimes and want to know if these oils will separate or do something bad...

I do remember that there are only some synthetics that mix with other brands synthetics. The only relavant info I have is that you can mix Royal Purple with Mobil 1...but I wouldn't mix the two you mentioned. If you want more help on this topic check out bobistheoilguy.com and sign up and search in the forums.

Canola Oil ftw

Edit: Facts & tests on BIO OIL! (Canola Oil based)

Edit #2: For those who don't want to sift through the whole article.

Canola-based motor oils have rapidly evolved into a competitive product. In terms of pricing, they are highly competitive with synthetic motor oils. They are also the most “environmentally friendly” of the motor oils available maintaining properties of non-toxicity and biodegradability. In terms of functionality, they have exceeded expectations by surpassing both conventional and synthetic oils in the tests conducted. As a low friction fluid, these tests indicate vegetable motor oils, or bio-oils, are a competitive product in modern engine applications.

A pleasant surprise has been the response of engines in terms of tailpipe and manifold gas emissions. The reductions in nitrous oxides, carbon monoxide, non-methane hydrocarbons, and hydrocarbons provide an easy and effective way to reduce air pollution. The value of these exhaust emissions has now become established and, in effect, may have more value than the oil itself. The impact of conversion to a bio-based motor oil for each million automobiles driven 18,590,000,000 km per year (17,699 km per vehicle) would be staggering. Hydrocarbons from automotive exhaust would be reduced annually by 1,101 t; carbon monoxide would be reduced by 87,475 t; and nitrous oxides would be reduced by 1,416 t.
